12.3.37 SP_get_list_n_bytes()

Synopsis

#include <sicstus/sicstus.h>

int
SP_get_list_n_bytes(SP_term_ref term,
                    SP_term_ref tail,
                    size_t n,
                    size_t *w,
                    unsigned char *s);

Copies into the byte array s the initial elements of term, which should hold a list of integers in the range [0,255], 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.

Arguments

term

The SP_term_ref holding the 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.
