$Revision$ $Date$ Purpose of this parser is to parse body of To header field. The parser can be found in file parse_to.c under parser subdirectory. Main function is parse_to but there is no need to call the function explicitly. Every time the parser finds a To header field, this function will be called automatically. Result of the parser is to_body structure. Pointer to the structure will be stored in parsed field of hdr_field structure. Since the pointer is void*, there is a convenience macro get_to in file parse_to.h that will do the necessary type-casting and will return pointer to to_body structure. The parser itself is a finite state machine that will parse To body according to the grammar defined in RFC3261 and store result in to_body structure. The parser gets called automatically from function get_hdr_field in file msg_parser.c. The function first creates and initializes an instance of to_body structure, then calls parse_to function with the structure as a parameter and if everything went OK, puts the pointer to the structure in parsed field of hdr_field structure representing the parsed To header field. The newly created structure will be freed when the message is being destroyed, see function clean_hdr_field in file hf.c for more details. See for detailed description of the data structure produced by this parser.
