.TH array_length 3 |

.SH NAME |
|
array_length \- get number of allocated members in array |
|
.SH SYNTAX |
|
.B #include <array.h> |
|
|
|
int64 \fBarray_length\fP(array* \fIx\fR,uint64 \fImembersize\fR); |
|
|
|
array \fIx\fR; |
|
int64 members = array_length(&\fIx\fR,sizeof(\fIt\fR)); |
|
|
|
.SH DESCRIPTION |
|
array_length returns the number of initialized bytes in \fIx\fR, divided |
|
by the size of \fIt\fR. In other words, array_get will succeed for |
|
positions 0 through array_length-1; it will fail for position |
|
array_length. |
|
|
|
If \fIx\fR is unallocated, array_length and array_bytes return 0. |
|
.SH "SEE ALSO" |
|
array_allocate(3), array_get(3), array_fail(3), array_bytes(3)
