do_hex_dump()

    #include <mplib1/dumphex.h>

    int do_hex_dump( FILE *fp, off_t curoff,
		    const char *where, int how_much );

This function outputs to the requested file a given block of memory in hexadecimal format, with and valid ASCII characters also displayed.

The memory to be display is pointed to by the where pointer, but the 'address' displayed will be based on the curoff parameter. This is of most use when display the details of a shared memory block like the SODB code.

So, if there is a block of shared memory which starts at some address pointed to by memblk and we want to display the contents of some portion of the block.

    do_hex_dump( stdout, 0x708, memblk+0x708, 0x70 );

The output would look like

00000708  .. .. .. .. .. .. .. .. 00 00 07 54 00 00 06 c8   '           T    '
