MGL_fseek

Repositions the file pointer on a stream.

Declaration

int MGLAPI MGL_fseek(
FILE *f,
long offset,
int whence)

Prototype In

mgraph.h

Parameters

f | Stream of interest
offset | Offset of location from whence
whence | New location of file pointer

Return Value

0 if move was successful, otherwise non-zero.

Description

This function is identical to the C library fseek function, but goes via MGL's internal file handling function pointers, which by default simply point to the standard C library functions. These functions are intended to allow the application programmer to override all the MGL file I/O functions with MGL_setFileIO, for custom I/O handling.
