$Revision: 5.0.2.2 $

Function

Package: FOREIGN-FUNCTIONS

Arguments: (address)

Returns the length of the C string located at address. This function is useful when calling char*-to-string with the optional string argument specified. Since the length of the Lisp string provided as the receptacle of the C string is not modified, you may not know how much was copied from the C string without the aid of this function.
