Standard C Library Functionsputspent(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;
long            sp_lstchg;
long            sp_min;
long            sp_max;
long            sp_warn;
long            sp_inact;
long            sp_expire;
unsigned long   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.
