gd_parser_callback(3) GETDATA gd_parser_callback(3)NAMEgd_parser_callback — set the syntax error callback handler for a
dirfile
SYNOPSIS
#include <getdata.h>
void gd_parser_callback(DIRFILE *dirfile, gd_parser_callback_t
sehandler, void *extra);
DESCRIPTION
The gd_parser_callback() function updates the syntax error callback
function of the DIRFILE object dirfile to be sehandler, and the caller
supplied extra pointer passed to the handler to be extra, discarding
any syntax error handler and extra pointer which were previously regis‐
tered for this DIRFILE. If sehandler is NULL, the existing handler
will be removed and the default behaviour (abort on error) restored.
See gd_cbopen(3) for a discussion on the requirements for the syntax
handler.
Since parsing of an existing format specification occurs when the
DIRFILE object is created, before this function can be called, this
function is only useful to set or modify a callback function or its
caller data before calling gd_include(3), which will invoke the call‐
back function if syntax errors are found in the included fragment.
This function always succeeds, and has no return value.
