NAME

putspent − write shadow password file entry

SYNOPSIS

#include <shadow.h>

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

DESCRIPTION

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

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

SEE ALSO

getspent(3C), getpwent(3C), putpwent(3C)

DIAGNOSTICS

The putspent routine returns non-zero if an error was detected during its operation, otherwise zero. 

NOTES

This routine is for internal use only, compatibility is not guaranteed.
