RLE_ROW_ALLOC(3) 3 (2/2/87) RLE_ROW_ALLOC(3)
NAME
rle_row_alloc - Allocate scanline memory for rle_putrow or
rle_getrow.
rle_row_free - Free scanline memory allocated by
rle_row_alloc.
SYNOPSIS
#include <rle.h>
rle_row_alloc( the_hdr, scanp )
rle_hdr * the_hdr;
rle_pixel *** scanp;
rle_row_free( the_hdr, scanp )
rle_hdr * the_hdr;
rle_pixel ** scanp;
DESCRIPTION
The function rle_row_alloc is provided to make it easier to
allocate storage for use by the RLE functions. It examines
the the_hdr structure provided and returns (via its other
argument) newly allocated space suitable for reading from or
writing to an RLE file described by the the_hdr structure.
rle_row_alloc allocates (the_hdr->xmax + 1) bytes for each
scanline, to allow for rle_getrow usage. Only those rows
enabled by the bit-map in the_hdr will have memory
allocated.
To free memory allocated by rle_row_alloc(3), call
rle_row_free with the pointer to the allocated storage.
