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 VALUEThe 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.ERRORSENOMEM Insufficient memory to allocate passwd structure.FILES/etc/passwd password database fileCONFORMING TOSVr4.SEE ALSOendpwent(3), fgetpwent_r(3), fopen(3), getpw(3), getpwent(3), getpwnam(3), getpwuid(3), putpwent(3), setpwent(3), passwd(5)COLOPHONThis page is part of release 3.53 of the Linux man-pages project.
