.TH array_get 3
.SH NAME
array_get \- get pointer to nth element in array
.SH SYNTAX
.B #include <array.h>

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

  array \fIx\fR;
  int64 \fIpos\fR;
  \fIt\fR* p = array_get(&\fIx\fR,sizeof(\fIt\fR),\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.

array_allocate(3), array_fail(3), array_start(3)
