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 get-
spnam(), 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 correspond-
ing /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.
