SYNOPSIS

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 stream must have the same format as /etc/passwd.

The passwd structure is defined in <pwd.h> as follows:

struct passwd {
    char   *pw_name;       /* user name */
    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
