Does anyone know file handling using GTK. I need to open a file in "w+" mode and write to it. I dont know if file handling exists in GTK. Below is a sample 'C' program that I need in GTK format.
#include <stdio.h> int main(int argc, char *argv[]) { int a = 5; float b = 3.14; FILE *fp; fp = fopen( "test.txt", "w+" ); fprintf( fp, " %d %f", a, b ); fwrite(----); fclose( fp ); } I'm sure you mean GIO
#include <gtk/gtk.h> int main(int argc, char *argv[]) { gtk_init(&argc,&argv); GFile *file=g_file_new_for_path("test.txt"); GFileOutputStream *output=g_file_replace( file,NULL,FALSE, G_FILE_CREATE_NONE, NULL,NULL); gint a=5; gfloat b=3.14; gchar *buf=g_strdup_printf(" %d %f",a,b); g_output_stream_write(G_OUTPUT_STREAM(output), buf,strlen(buf),NULL,NULL); /* ----- */ g_output_stream_close(G_OUTPUT_STREAM(output),NULL,NULL); g_free(buf); g_object_unref(output); g_object_unref(file); return 0; } I won't explain any function,see GIO Reference Manual(do you know Devhelp?) for more detials
As said above, GTK is for user interfaces, and your code sample has no graphical user interface. However, you may give a look to GLib, the underlying library that powers GTK. There are file utilities functions, good for portability across systems, and portable I/O channels.
