rle_row_alloc - Allocate scanline memory for rle_putrow or rle_getrow.
rle_row_free - Free scanline memory allocated by rle_row_alloc.
rle_row_alloc( the_hdr, scanp )
rle_row_free( the_hdr, scanp )
rle_hdr * the_hdr;
rle_pixel ** scanp;
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.
