pack_fread(3alleg4)						  Allegro manual					       pack_fread(3alleg4)

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.

NAME

       expackf - Using custom PACKFILE vtables. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       Example expackf

DESCRIPTION

       This program demonstrates the use of the packfile functions, with some simple tests.

       The  first  test  uses  the  standard packfile functions to transfer a bitmap file into a block of memory, then reads the bitmap out of the
       block of memory, using a custom packfile vtable.

       The second test reads in a bitmap with another custom packfile vtable, which uses libc's file stream functions.

       The third test demonstrates seeking with a custom vtable.

       The fourth test reads two bitmaps, and dumps them back into a single file, using a custom vtable again.
