- /* is not wasteful of memory at all because FunnelWeb requires random access */
- /* to each input file at all times anyway so it can scramble the text around. */

- /* Allocates a block of memory and places a Unix text stream representation */
- /* (with EOL marking end of line and no character marking end of file) of the */
- /* file 'p_name' in the block of memory. Returns a pointer to the address and */
- /* len of the file in the mem block in the parameters (pp_mem and p_length). */
- /* Returns NULL upon success or a pointer to an error message string upon */
- /* failure. Note: Parameters are: p_name, pp_mem, p_length. */
- /* Note: Allocates enough memory so that there is guaranteed to be at least */
- /* two extra bytes of spare memory at the end of the mapped file. The */
- /* scanner uses this space to put EOL and EOF characters. */
- /* Note: The mapper grabs its memory using mm_temp, so it can be recycled */
