putspent(S)

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.

Return values

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