SYNOPSIS

11     #include <ck_array.h>
12
13     int
14     ck_array_put_unique(ck_array_t *array, void *pointer);
15

DESCRIPTION

17     The ck_array_put_unique(3) function will attempt to insert the value of
18     pointer into the array pointed to by array.  This function may incur
19     additional memory allocations if not enough memory has been allocated in
20     the array for a new entry. The operation is also free to apply the opera‐
21     tion immediately if there is an opportunity for elimination with a pend‐
22     ing (uncommitted) remove operation. The function will not make any modi‐
23     fications if the pointer already exists in the array.
24

RETURN VALUES

26     This function returns 1 if the pointer already exists in the array.  It
27     returns 0 if the put operation succeeded. It returns -1 on error due to
28     internal memory allocation failures.
