#include <ast.h>
void mematoe(void* \fIout\fP, const void* \fIin\fP, size_t \fIn\fP);
void* memdup(const void* \fIbuf\fP, size_t \fIn\fP)

.SH DESCRIPTION
.L mematoe
converts
.I n
ASCII characters in
.I in
to EBCDIC characters in
.IR out .
.I in
and
.I out
may be the same.
.PP
.L memdup
copies the
.I n
byte buffer
.I buf
to a new location provided by
.IR malloc (3)
and returns a pointer to the new copy.
0 is returned if
.IR malloc (3)
fails.
.PP
.L memetoa
converts
.I n
EBCDIC characters in
.I in
to ASCII characters in
.IR out .
.I in
and
.I out
may be the same.
.PP
.L memzero
sets the first
.I n
bytes in
.I buf
to
.IR 0 .
