MEMINS(3)		     C Programmer's Manual		     MEMINS(3)

NAME
       memins -	insert bytes at	beginning of memory block

SYNOPSIS
       #include	<publib.h>
       void *memins(void *tgt, size_t tgtsize, const void *src,	size_t srcsize);

DESCRIPTION
       memins  inserts	srcsize	 bytes	from  src at the beginning of tgt, but
       moves the first tgtsize out of the way.	The source and	target	memory
       blocks must not overlap.

RETURN VALUE
       memins returns its first	argument.

EXAMPLE
       To  insert  a new element at the	ith position of	an array, one might do
       the following.

	    int	new, array[10];

	    memins(array+i, (10-i-1)*sizeof(array[0]), &new, sizeof(new));

       Please note that	the above code carefully avoids	the trap of moving the
       last element of the array past the end of the array.
