NAME
pack_fread - Reads n bytes from the stream. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
long pack_fread(void *p, long n, PACKFILE *f);
DESCRIPTION
Reads `n' bytes from the stream `f', storing them at the memory location pointed to by `p'. Example:
unsigned char buf[256];
...
if (pack_fread(buf, 256, input_file) != 256)
abort_on_error("Truncated input file!");
RETURN VALUE
Returns the number of bytes read, which will be less than `n' if EOF is reached or an error occurs. Error codes are stored in errno.
