.SH NAME

array_truncate \- reduce number of initialized bytes

.SH SYNTAX

.B #include <libowfat/array.h>
|
|
|
|
void \fBarray_truncate\fP(array* \fIx\fR, uint64 \fImembersize\fR, int64 \fIlen\fR);
|
|
|
|
array_truncate(&\fIx\fR,sizeof(\fIt\fR),\fIlen\fR);
|
|
|
|
.SH DESCRIPTION
|
|
array_truncate reduces the number of initialized bytes in \fIx\fR to
|
|
exactly \fIlen\fR*sizeof(\fIt\fR). If the number of initialized bytes
|
|
was already this small (or smaller), array_truncate has no effect. If
|
|
\fIlen\fR is negative, array_truncate has no effect. If \fIx\fR is
|
|
unallocated, array_truncate has no effect. If \fIx\fR has failed,
|
|
array_truncate has no effect.
|
|
|
|
array_truncate does not change the allocation in \fIx\fR. If you want to free
|
|
the memory used by \fIx\fR, use array_reset.
