Note:
I M P O R T A N T :
The speed of extension handling will likely be among the most important aspects of this PBX. The switching scheme as it exists right now isn't terribly bad (it's O(N+M), where N is the # of extensions and M is the avg # of priorities, but a constant search time here would be great ;-)

Enumeration Type Documentation

enum ext_match_t

When looking up extensions, we can have different requests identified by the 'action' argument, as follows. Note that the coding is such that the low 4 bits are the third argument to extension_match_core.

Enumerator:
E_MATCHMORE 
E_CANMATCH 
E_MATCH 
E_MATCH_MASK 
E_SPAWN 
E_FINDLABEL

Add an extension to an extension context, this time with an ast_context *.

We sort extensions in order of matching preference, so that we can stop the search as soon as we find a suitable match. This ordering also takes care of wildcards such as '.' (meaning "one or more of any character") and '!' (which is 'earlymatch', meaning "zero or more of any character" but also impacts the return value from CANMATCH and EARLYMATCH.

The extension match rules defined in the devmeeting 2006.05.05 are quite simple: WE SELECT THE LONGEST MATCH. In detail, "longest" means the number of matched characters in the extension. In case of ties (e.g. _XXX and 333) in the length of a pattern, we give priority to entries with the smallest cardinality (e.g, [5-9] comes before [2-8] before the former has only 5 elements, while the latter has 7, etc. In case of same cardinality, the first element in the range counts. If we still have a tie, any final '!' will make this as a possibly less specific pattern.

EBUSY - can't lock EEXIST - extension with the same priority exist and no replace is set

Looks for a valid matching extension.

Parameters:

exten extension to check
priority priority of extension path
callerid callerid of extension being searched for
Returns:
If "exten" *could be* a valid extension in this context with or without some more digits, return non-zero. Basically, when this returns 0, no matter what you add to exten, it's not going to be a valid extension anymore

struct ast_context* ast_context_create ( struct ast_context **  extcontexts,
const char *  name,

Register a new context.

Parameters:
extcontexts pointer to the ast_context structure pointer
name name of the new context
registrar registrar of the context
This will first search for a context with your name. If it exists already, it will not create a new one. If it does not exist, it will create a new one with the given name and registrar.

Returns:
NULL on failure, and an ast_context structure on success

Destroy a context (matches the specified context (or ANY context if NULL).

Parameters:
con context to destroy
registrar who registered it
You can optionally leave out either parameter. It will find it based on either the ast_context or the registrar name.

Returns:

extension which extension to remove
priority priority of extension to remove (0 to remove all)
callerid NULL to remove all; non-NULL to match a single record per priority
matchcid non-zero to match callerid element (if non-NULL); 0 to match default case

This functionc locks given context, search for the right extension and fires out all peer in this extensions with given priority. If priority is set to 0, all peers are removed. After that, unlock context and return.

Note:
When do you want to call this function, make sure that &conlock is locked, because some process can handle with your *con context before you lock it.

int ast_extension_state_add ( const char *  context,
const char *  exten,
ast_state_cb_type  callback,
void *  data 
)

Registers a state change callback.

Parameters:
context which context to look in
exten which extension to get state
callback callback to call if state changed
data to pass to callback
The callback is called if the state of an extension is changed.

Return values:
-1 on failure
ID on success

int ast_findlabel_extension ( struct ast_channel c,
const char *  context,
const char *  exten,
const char *  label,
const char *  callerid 
)

Find the priority of an extension that has the specified label.

Parameters:
c this is not important
context which context to look in
exten which extension to search for
label label of the action within the extension to match to priority
callerid callerid to search for
Returns:
the priority which matches the given label in the extension or -1 if not found.

int ast_findlabel_extension2 ( struct ast_channel c,

Find the priority of an extension that has the specified label.

Note:
This function is the same as ast_findlabel_extension, except that it accepts a pointer to an ast_context structure to specify the context instead of the name of the context. Otherwise, the functions behave the same.

int ast_ignore_pattern ( const char *  context,
const char *  pattern

Checks to see if a number should be ignored.

Parameters:
context context to search within
pattern to check whether it should be ignored or not
Check if a number should be ignored with respect to dialtone cancellation.

Return values:
0 if the pattern should not be ignored
non-zero if the pattern should be ignored

int ast_matchmore_extension ( struct ast_channel c,
const char *  context,
const char *  exten,
int  priority,
const char *  callerid 
)

Looks to see if adding anything to this extension might match something. (exists ^ canmatch).

Parameters:
c not really important XXX
context context to serach within
exten extension to check
priority priority of extension path
callerid callerid of extension being searched for
Returns:
If "exten" *could match* a valid extension in this context with some more digits, return non-zero. Does NOT return non-zero if this is an exact-match only. Basically, when this returns 0, no matter what you add to exten, it's not going to be a valid extension anymore

void ast_merge_contexts_and_delete ( struct ast_context **  extcontexts,

Merge the temporary contexts into a global contexts list and delete from the global list the ones that are being added.

Parameters:
extcontexts pointer to the ast_context structure pointer
registrar of the context; if it's set the routine will delete all contexts that belong to that registrar; if NULL only the contexts that are specified in extcontexts

enum ast_pbx_result ast_pbx_run ( struct ast_channel c  ) 

Execute the PBX in the current thread.

Parameters:
c channel to run the pbx on
This executes the PBX on a given channel. It allocates a new PBX structure for the channel, and provides all PBX functionality. See ast_pbx_start for an asynchronous function to run the PBX in a new thread as opposed to the current one.

Returns:
Zero on success, non-zero on failure

static int ext_cmp1 ( const char **  p  )  [static]

helper functions to sort extensions and patterns in the desired way, so that more specific patterns appear first.

ext_cmp1 compares individual characters (or sets of), returning an int where bits 0-7 are the ASCII code of the first char in the set, while bit 8-15 are the cardinality of the set minus 1. This way more specific patterns (smaller cardinality) appear first. Wildcards have a special value, so that we can directly compare them to sets by subtracting the two values. In particular: 0x000xx one character, xx 0x0yyxx yy character set starting with xx 0x10000 '.' (one or more of anything) 0x20000 '!' (zero or more of anything) 0x30000 NUL (end of string) 0x40000 error in set. The pointer to the string is advanced according to needs. NOTES: 1. the empty set is equivalent to NUL. 2. given that a full set has always 0 as the first element, we could encode the special cases as 0xffXX where XX is 1, 2, 3, 4 as used above.

enum ext_match_t  action 
) [static]

The return value depends on the action:.

E_MATCH, E_CANMATCH, E_MATCHMORE require a real match, and return 0 on failure, -1 on match; E_FINDLABEL maps the label to a priority, and returns the priority on success, ... XXX E_SPAWN, spawn an application, and return 0 on success, -1 on failure.

Note:
The channel is auto-serviced in this function, because doing an extension match may block for a long time. For example, if the lookup has to use a network dialplan switch, such as DUNDi or IAX2, it may take a while. However, the channel auto-service code will queue up any important signalling frames to be processed after this is done.

static char* substring ( const char *  value,

takes a substring. It is ok to call with value == workspace.

offset < 0 means start from the end of the string and set the beginning to be that many characters back. length is the length of the substring. A value less than 0 means to leave that many off the end. Always return a copy in workspace.
