void* \fBarray_get\fP(array* \fIx\fR, uint64 \fImembersize\fR, int64 \fIpos\fR);

.SH DESCRIPTION
|
||
|
|
array_get is similar to array_allocate, but it does not allocate any
|
||
|
|
extra bytes, and it does not initialize any extra bytes. It returns 0
|
||
|
|
if \fIx\fR is unallocated, for example, or if fewer than
|
||
|
|
(\fIpos\fR+1)*sizeof(\fIt\fR) bytes are initialized.
|
||
|
