Hi Damien,
Thanks for your reply.
What I have ended up with is something like:
FILE *fopf = fopen(filename, "a" );
if (!fopf){
filename="Untitled.bib";
fopf= fopen(filename,"a");
}
char buffer[]="Hello World";
int buf_size= strlen(buffer)+1;
fwrite(buffer,buf_size,1,fopf);
if(!buffer){
printf("failed");
}
// fclose(fopf);
GString *fop=g_string_new(NULL);
g_string_append_printf( fop,buffer);
gtk_label_set_text(GTK_LABEL(flabel), filename);
g_string_append_printf( fop, "@%s{%s,\n", strcombo, strkey );
if( strlen(strAuth)!=0)
g_string_append_printf( fop, "\tAuthor=\"%s\",\n", strAuth);
if( strlen(strEditor)!=0)
g_string_append_printf( fop, "\tEditor=\"%s\",\n", strEditor);
if( strlen(strSchool)!=0)
g_string_append_printf( fop, "\tSchool=\"%s\",\n", strSchool);
g_string_append_printf( fop, "}\n");
// fclose(fop);
g_file_set_contents(filename,
fop,
1026,
NULL);
}
But this writes the data in unformatted form.
Can you kindly explain a bit more?
