.TH iarray_get 3
.SH NAME
iarray_get \- get pointer to nth element in iarray
.SH SYNTAX
.B #include <libowfat/iarray.h>
13 years ago
void* \fBiarray_get\fP(iarray* \fIx\fR, size_t \fIpos\fR);
iarray \fIx\fR;
size_t \fIpos\fR;
\fIt\fR* p = iarray_get(&\fIx\fR,\fIpos\fR);
.SH 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.
.SH "RETURN VALUE"
Return a pointer to the requested element. If there is no such element
in the array, returns NULL.
.SH "SEE ALSO"
iarray_init(3), iarray_allocate(3), iarray_free(3)
