Expand description

Calls a function once for each value in the array.

Parameter theArray: The array to be operated upon. If this parameter is not a valid CFArray, the behavior is undefined.

Parameter range: The range of values within the array to which to apply the function. If the range location or end point (defined by the location plus length minus 1) is outside the index space of the array (0 to N-1 inclusive, where N is the count of the array), the behavior is undefined. If the range length is negative, the behavior is undefined. The range may be empty (length 0).

Parameter applier: The callback function to call once for each value in the given range in the array. If this parameter is not a pointer to a function of the correct prototype, the behavior is undefined. If there are values in the range which the applier function does not expect or cannot properly apply to, the behavior is undefined.

Parameter context: A pointer-sized user-defined value, which is passed as the second parameter to the applier function, but is otherwise unused by this function. If the context is not what is expected by the applier function, the behavior is undefined.
