SYNTAX
#include <pwd.h>
int putpwent(p, f)
struct passwd *p;

DESCRIPTION
The putpwent subroutine is the inverse of getpwent(3). Given a pointer to a passwd structure created by getpwent, getpwuid, or getpwnam, putpwent writes a line on the stream f, which matches the format of /etc/passwd.
DIAGNOSTICS
The putpwent subroutine returns non-zero if an error was detected during its operation, otherwise zero.
