void ast_filestream_frame_freed | ( | struct ast_frame * | fr | ) |
destroy a filestream using an ast_frame as input
This is a hack that is used also by the ast_trans_pvt and ast_dsp structures. When a structure contains an ast_frame pointer as one of its fields. It may be that the frame is still used after the outer structure is freed. This leads to invalid memory accesses. This function allows for us to hold off on destroying the ast_filestream until we are done using the ast_frame pointer that is part of it
