fopen

A wrapper for the stdio fopen() function. The fopen() function opens a file and associates a new stream with it.

Because file descriptors are specific to the C library on Windows, and a file descriptor is part of the FILE struct, the FILE* returned by this function makes sense only to functions in the same C library. Thus if the GLib-using code uses a different C library than GLib does, the FILE* returned by this function cannot be passed to C library functions like fprintf() or fread().

See your C library manual for more details about fopen().

As close() and fclose() are part of the C library, this implies that it is currently impossible to close a file if the application C library and the C library used by GLib are different. Convenience functions like glib.global.fileSetContentsFull avoid this problem.
