NAME¶
iarray_get - get pointer to nth element in iarray
SYNTAX¶
#include <iarray.h>
void*
iarray_get(iarray*
x, size_t
pos);
iarray
x;
size_t
pos;
t* p = iarray_get(&
x,
pos);
DESCRIPTION¶
iarray_get is similar to iarray_allocate, but it only works if the element has
previously been allocated. If the element in the iarray is not there, this
function will fail instead of manipulating the iarray. This also guarantees
that there will be no locks, so this function returns in a deterministic time.
RETURN VALUE¶
Return a pointer to the requested element. If there is no such element in the
array, returns NULL.
