DESCRIPTION The getpwnam() function returns a pointer to a structure
containing the broken out fields of a line from
/etc/passwd for the entry that matches the user name name.
The getpwuid() function returns a pointer to a structure
containing the broken out fields of a line from
/etc/passwd for the entry that matches the user uid uid.
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 getpwnam() and getpwuid() functions return the passwd
structure, or NULL if the matching entry is not found or
an error occurs.
ERRORS ENOMEM Insufficient memory to allocate passwd structure.
