string-to-char*

Function

Package: ff

Arguments: string &optional address

This function is obsolete. It has been replaced by string-to-native. A call to string-to-char* has been changed to return the first value of the following:

(excl:string-to-native string 
                       :address address 
                       :external-format :default)

Users are encouraged to use string-to-native instead of string-to-char* for new code. See also native-to-string and with-native-string.

The remainder of this description is the old documentation for string-to-char*.

This function returns an integer pointer to a C string. string should be a Lisp string. If the optional address argument is used, then string-to-char* copies string to address.

This function uses malloc to allocate the space needed for the string. This space will not be freed automatically by Lisp. Users must free the space themselves, by calling aclfree with the address returned by string-to-char* as the single argument.
