## char*-strlen

Arguments: address &optional aligned

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.

If the optional aligned argument is true, then address is an aligned address. Aligned addresses are returned by functions like lispval-to-aligned-malloc-address.
