#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 .
