NAME¶
fgetpwent - get password file entry
SYNOPSIS¶
#include <stdio.h> #include <sys/types.h> #include <pwd.h>
struct passwd *fgetpwent(FILE *stream);
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 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. In the event of an error, errno is set to indicate the cause.
ERRORS¶
- ENOMEM
 - Insufficient memory to allocate passwd structure.
 
FILES¶
- /etc/passwd
 - password database file
