Re: write to a file using g_print

[Ardhan Madras <ardhan rocksis net>]

g_open() is wrapper to open() syscall, not the standard libc's fopen().

You got this because g_open() returning a int (file descriptor) not a
FILE pointer.

You must distinguish each I/O method that you are using and don't mess with it.
You can't use a file descriptor to standard libc's I/O functions, use
FILE pointer instead.

#include <glib.h>
#include <glib/gstdio.h>
#include <stdio.h>

FILE *fop = open("bib2.bib", "w");
/* you can call g_fprintf() or fprintf() */

see man 3 printf

g_print() already write to standard output FILE, but you can dup()
standard output to another file.
