CK_ARRAY_PUT_UNIQUE(3) BSD Library Functions Manual CK_ARRAY_PUT_UNIQUE(3)NAMEck_array_put_unique — attempt immediate or deferred insertion of a unique
pointer into array
LIBRARY
Concurrency Kit (libck, -lck)
SYNOPSIS
#include <ck_array.h>
int
ck_array_put_unique(ck_array_t *array, void *pointer);
DESCRIPTION
The ck_array_put_unique(3) function will attempt to insert the value of
pointer into the array pointed to by array. This function may incur
additional memory allocations if not enough memory has been allocated in
the array for a new entry. The operation is also free to apply the opera‐
tion immediately if there is an opportunity for elimination with a pend‐
ing (uncommitted) remove operation. The function will not make any modi‐
fications if the pointer already exists in the array.
RETURN VALUES
This function returns 1 if the pointer already exists in the array. It
returns 0 if the put operation succeeded. It returns -1 on error due to
internal memory allocation failures.
