MGL_fread

Reads data from a stream.

Declaration

size_t MGLAPI MGL_fread(
void *ptr,
size_t size,
size_t n,
FILE *f)

Prototype In

mgraph.h

Parameters

ptr | Pointer to block in stream at which to begin read
size | Size of items to be read from stream
n | Number of items to be read from stream
f | Stream to be read

Return Value

Number of items read in, or a short count (possibly 0).

Description

This function is identical to the C library fread function, but goes via the MGL's internal file handling function pointers, which by default simply points 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.
