PUTSPENT(3C) Standard C Library Functions PUTSPENT(3C)

NAME

putspent - write shadow password file entry

SYNOPSIS

#include <shadow.h>

int putspent(const struct spwd *p, FILE *fp);

DESCRIPTION

The putspent() function is the inverse of getspent(). See
getspnam(3C). Given a pointer to a spwd structure created by
getspent() or getspnam(), putspent() writes a line on the stream fp
that matches the format of /etc/shadow.


The spwd structure contains the following members:

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;


If the sp_min, sp_max, sp_lstchg, sp_warn, sp_inact, or sp_expire
member of the spwd structure is -1, or if sp_flag is 0, the
corresponding /etc/shadow field is cleared.

RETURN VALUES

The putspent() function returns a non-zero value if an error was
detected during its operation. Otherwise, it returns 0.

USAGE

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 putpwent(3C) to update the password file.
