map_array(3)           C LIBRARY FUNCTIONS           map_array(3)

NAME
     map_array() - modify an array of elements via application of
     a function

SYNOPSIS
     mixed *map_array(mixed *arr, string fun,  object  ob,  mixed
     extra);

DESCRIPTION
     Returns an array holding the items of `arr'  mapped  through
     `ob->fun()'.   The function `fun' in `ob' is called for each
     element in `arr' with that element as  parameter.  A  second
     parameter  `extra'  is sent in each call if given. Principal
     function:

          `foreach      (index)      arr[index]       =       ob-
          >fun(arr[index],extra);'

     The  value  returned   by   `ob->fun(arr[.index.],   extra)'
     replaces  the existing element in the array. If `arr' is not
     an array, then 0 will be returned.
