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.
