Re: glib and relative file names

[Larry Reaves <larry yrral net>]

pwd.c:
#include <glib.h>

int main(int argc, char **argv) {
 gchar *cwd = g_get_current_dir();

 g_print("%s\n", cwd);

 g_free(cwd);

 return 0;
}

gcc -o pwd pwd.c `pkg-config --cflags --libs glib-2.0`

Works for me.

This should work for converting to absolute path in the event you
detect a relative filename:

gchar *cwd = g_get_current_dir();
gchar *fn = g_build_filename (cwd, argv[i], NULL);
g_free(cwd);
 //use fn here
g_free(fn);

Depending on your platform, you can either just check for a leading /
or [A-Z]:\... or add an else clause to your existence check and
recheck with the full filename.  Just don't forget to free any gchar*
variables you might allocate with get_current_dir or build_filename
;).  Hope that helps.
