.SH NAME
putspent \- write shadow password file entry
.SH SYNOPSIS
.LP
.nf
#include <shadow.h>

\fBint\fR \fBputspent\fR(\fBconst struct spwd *\fR\fIp\fR, \fBFILE *\fR\fIfp\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The  \fBputspent()\fR function is the inverse of \fBgetspent()\fR. See \fBgetspnam\fR(3C). Given a pointer to a \fBspwd\fR structure created by \fBgetspent()\fR or \fBgetspnam()\fR, \fBputspent()\fR writes a line on the stream \fIfp\fR that matches the format of \fB/etc/shadow\fR.
.sp
.LP
The \fBspwd\fR structure contains the following members:
.sp
.in +2
.nf
char           *sp_namp;
char           *sp_pwdp;
int            sp_lstchg;
int            sp_min;
int            sp_max;
int            sp_warn;
int            sp_inact;
int            sp_expire;
unsigned int   sp_flag;
.fi
.in -2

.sp
.LP
If the \fBsp_min\fR, \fBsp_max\fR, \fBsp_lstchg\fR, \fBsp_warn\fR, \fBsp_inact\fR, or \fBsp_expire\fR member of the  \fBspwd\fR structure is \(mi1, or if \fBsp_flag\fR is 0, the corresponding \fB/etc/shadow\fR field is cleared.
.SH RETURN VALUES
.sp
.LP
The  \fBputspent()\fR function returns a non-zero value if an error was detected during its operation. Otherwise, it returns \fB0\fR.
.SH USAGE
.sp
.LP
Since this function is for internal use only, compatibility is not guaranteed. For this reason, its use is discouraged. If used at all, if should be used with \fBputpwent\fR(3C) to update the password file.
