A wrapper for calloc() for use in cache pools.
ast_calloc_cache() is a wrapper for calloc() that will generate an Asterisk log message in the case that the allocation fails. When memory debugging is in use, the memory allocated by this function will be marked as 'cache' so it can be distinguished from normal memory allocations.
The arguments and return value are the same as calloc()

ast_strdup() is a wrapper for strdup() that will generate an Asterisk log message in the case that the allocation fails.

#define ast_strndup | ( | str, | |||

A wrapper for strndup().
ast_strndup() is a wrapper for strndup() that will generate an Asterisk log message in the case that the allocation fails.
ast_strndup(), unlike strndup(), can safely accept a NULL argument for the string to duplicate. If a NULL argument is provided, ast_strdup will return NULL without generating any kind of error log message.
The arguments and return value are the same as strndup()

unsigned int __unsigned_int_flags_dummy |
Note: It is very important to use only unsigned variables to hold bit flags, as otherwise you can fall prey to the compiler's sign-extension antics if you try to use the top two bits in your variable. The flag macros below use a set of compiler tricks to verify that the caller is using an "unsigned int" variable to hold the flags, and nothing else. If the caller uses any other type of variable, a warning message similar to this: warning: comparison of distinct pointer types lacks cast will be generated. The "dummy" variable below is used to make these comparisons. Also note that at -O2 or above, this type-safety checking does _not_ produce any additional object code at all.
