.TH PUTPWENT 3C "Dec 29, 1996"
.SH NAME
putpwent \- write password file entry
.SH SYNOPSIS
.LP
.nf
#include <pwd.h>

\fBint\fR \fBputpwent\fR(\fBconst struct passwd *\fR\fIp\fR, \fBFILE *\fR\fIf\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBputpwent()\fR function is the inverse of \fBgetpwent()\fR. See
\fBgetpwnam\fR(3C). Given a pointer to a \fBpasswd\fR structure created by
\fBgetpwent()\fR, \fBgetpwuid()\fR, or \fBgetpwnam()\fR, \fBputpwent()\fR
writes a line on the stream \fIf\fR that matches the format of
\fB/etc/passwd\fR.
.SH RETURN VALUES
.sp
.LP
The \fBputpwent()\fR function returns a non-zero value if an error was detected
during its operation. Otherwise, it returns \fB0\fR.
.SH USAGE
.sp
.LP
The \fBputpwent()\fR function is of limited utility, since most password files
are maintained as Network Information Service (NIS) files that cannot be
updated with this function. For this reason, the use of this function is
discouraged. If used at all, it should be used with \fBputspent\fR(3C) to
update the shadow file.
