RLE_ROW_ALLOC(3)      DragonFly Library Functions Manual      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.
