write to a file using g_print
Is it possible to write to a file using g_print?
I was trying something like:
FILE *fop = g_open("bib2.bib","w");
g_print ("%s%s",strcombo,strkey, fop);
but its not working.
Even fprintf is giving warning and not writing.
mkbib.c:114:15: warning: initialization makes pointer from integer
without a cast [enabled by default]
mkbib.c:115:3: warning: passing argument 1 of ‘fprintf’ from
incompatible pointer type [enabled by default]
Any solution?

Quite the opposite. It sends messages to the print handler. Depending on the print handler stup, it do anything with them (print to stdout, save to some file, display somewhere, discard, ...). > Any solution? Don't do that then. Use g_fprintf(). Or, in most cases, just fprintf(). Yeti ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: write to a file using g_print
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
#include
#include
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.

Re: write to a file using g_print
Sorry my bad.
> FILE *fop = open("bib2.bib", "w");
It should be fopen()
