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.
