NAME

putpwent − write password file entry

SYNOPSIS

#include <pwd.h>

int putpwent (p, f)
struct passwd ∗p;
FILE ∗f;

DESCRIPTION

putpwent is the inverse of getpwent(3). Given a pointer to a passwd structure created by getpwent (or getpwuid or getpwnam), putpwent writes a line on the stream f, which matches the format of lines in the password file /etc/passwd. 

DIAGNOSTICS

putpwent returns non-zero if an error was detected during its operation, otherwise zero. 

SEE ALSO

getpwent(3). 

WARNING

The above routine uses <stdio.h>, which causes it to increase the size of programs, not otherwise using standard I/O, more than might be expected. 

BUGS

This routine is of limited utility, since most password files are maintained as Yellow Pages files, and cannot be updated with this routine.
