dirfile_parser_callback — set the syntax error callback handler for a dirfile

Synopsis

#include <getdata.h>
void dirfile_parser_callback(DIRFILE *dirfile, gd_parser_callback_t sehandler, void *extra);

Description

The dirfile_parser_callback() 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 registered for this DIRFILE. If sehandler is NULL, the existing handler will be removed and the default behaviour (abort on error) restored. See dirfile_cbopen(3) for a discussion on the requirements for the syntax handler.

Since parsing of an existing format file 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 dirfile_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.
