/*
 * Function:    calloc()
 *
 * Purpose: to allocate and nullify a data area
 *
 * Arguments:   nelem   - number of elements
 *      elsize  - size of each element
 *
 * Returns: NULL    - if malloc fails
 *      or pointer to allocated space
 *
 * Narrative:   determine size of area to malloc
 *      malloc area.
