NAME

     ck_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 operation immediately if there is an
     opportunity for elimination with a pending (uncommitted) remove operation. The function will not make any
     modifications 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.
