struct passwd *getpwent(void);
void setpwent(void);
void endpwent(void); The getpwent() function returns a pointer to a structure containing the broken out fields of a line from /etc/passwd. The first time it is called it returns the first entry; thereafter, it returns successive entries. The setpwent() function rewinds the file pointer to the beginning of the /etc/passwd file.
The endpwent() function closes the /etc/passwd file.
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 */
};
The getpwent() function returns the passwd structure, or NULL if there are no more entries or an error occurs. - ENOMEM
- Insufficient memory to allocate passwd structure.
