.TH iarray_get 3 |
|
.SH NAME |
|
iarray_get \- get pointer to nth element in iarray |
|
.SH SYNTAX |
|
.B #include <iarray.h> |
|
|
|
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)
