fgetpwent(3) [suse man page]

FGETPWENT(3)						     Linux Programmer's Manual						      FGETPWENT(3)

NAME
fgetpwent - get password file entry SYNOPSIS
#include <stdio.h> #include <sys/types.h> #include <pwd.h> struct passwd *fgetpwent(FILE *stream); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): fgetpwent(): _SVID_SOURCE DESCRIPTION
The fgetpwent() function returns a pointer to a structure containing the broken out fields of a line in the file stream. The first time it is called it returns the first entry; thereafter, it returns successive entries. The file referred to by stream must have the same format as /etc/passwd (see passwd(5)). The passwd structure is defined in <pwd.h> as follows: struct passwd { char *pw_name; /* username */ char *pw_passwd; /* user password */ uid_t pw_uid; /* user ID */ gid_t pw_gid; /* group ID */ char *pw_gecos; /* real name */ char *pw_dir; /* home directory */ char *pw_shell; /* shell program */ }; RETURN VALUE
The fgetpwent() function returns a pointer to a passwd structure, or NULL if there are no more entries or an error occurs. ERRORS
ENOMEM Insufficient memory to allocate passwd structure. FILES
/etc/passwd password database file CONFORMING TO
SVr4. SEE ALSO
endpwent(3), fgetpwent_r(3), fopen(3), getpw(3), getpwent(3), getpwnam(3), getpwuid(3), putpwent(3), setpwent(3), passwd(5) COLOPHON

NAME

#include <stdio.h> #include <sys/types.h> #include <pwd.h> struct passwd *fgetpwent(FILE *stream); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): fgetpwent(): Since glibc 2.19: _DEFAULT_SOURCE Glibc 2.19 and earlier: _SVID_SOURCE DESCRIPTION
The fgetpwent() function returns a pointer to a structure containing the broken out fields of a line in the file stream. The first time it is called it returns the first entry; thereafter, it returns successive entries. The file referred to by stream must have the same format as /etc/passwd (see passwd(5)).

The fgetpwent() function returns a pointer to a passwd structure, or NULL if there are no more entries or an error occurs. In the event of an error, errno is set to indicate the cause. ERRORS
ENOMEM Insufficient memory to allocate passwd structure. FILES
