putspent(3C)                      SDK R4.11                     putspent(3C)


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 spmin, spmax, splstchg, spwarn, spinact, or spexpire
       field of the spwd structure is -1, or if spflag is 0, the
       corresponding /etc/shadow field is cleared.
