NAME

       gd_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  reg-
       istered	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 func-
       tion  is  only  useful to set or modify a callback function or its caller data before calling gd_include(3), which will invoke the callback
       function if syntax errors are found in the included fragment.

       This function always succeeds, and has no return value.
