putspent(3C) — C LIBRARY FUNCTIONS
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.
