Tagged argument lists.
| #define SU_TAGARG_H |
Defined when <sofia-sip/su_tagarg.h> has been included.
| #define ta_args | ( | ta | ) |
Macro accessing tagged argument list.
The ta_args() returns a pointer to tag list containing the arguments.
| #define ta_end | ( | ta | ) |
Handle return from function with tagged argument list.
The ta_end() macro handles return from function whose tagged argument list was initialized by ta_start().
The ta_end() macro returns no value.
| #define ta_start | ( | ta, | ||
| t, | ||||
| v | ||||
| ) |
Macro initializing a ta_list object.
The ta_start() macro initializes ta for subsequent use by ta_args(), ta_tags() and ta_end(), and must be called first.
The parameters t and v are the names of the tag and value in the first tag list item before the variable argument list (...).
The ta_start() macro returns no value.
| #define ta_tags | ( | ta | ) |
Macro passing tagged argument list as an argument to another function.
The ta_tags() macro expands to an tag list that can be given as arguments to a function taking an variable tag item list as an argument.
