12.3.38 SP_get_list_n_codes()

Synopsis

     #include <sicstus/sicstus.h>
     
     int
     SP_get_list_n_codes(SP_term_ref term,
                         SP_term_ref tail,
                         size_t n,
                         size_t *w,
                         char *s);

Copies into s the encoded string representing the character codes in the initial elements of list term, so that at most n bytes are used. The number of bytes actually written is assigned to *w. tail is set to the remainder of the list. The array s must have room for at least n bytes.

Please note: The array s is never NUL-terminated. Any zero character codes in the list term will be converted to the overlong UTF-8 sequence 0xC0 0x80.

Arguments

term

The SP_term_ref holding the code-list

tail

The SP_term_ref to be assigned the remainder of the list

n

Max number of bytes to use

w

Location to assign to number of bytes actually used

s

The location to assign to the encoded string

Return Value

Zero if the conversion fails (as far as failure can be detected), and a nonzero value otherwise.
