char*-string-length

Arguments: address

This function is obsolete and maintained in the :ffcompat compatibility module, which is loaded automatically when this function is called. It has been replaced with char*-strlen. Using char*-strlen means fewer modules need be present in an image using this functionality.

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.
