/*** GET_ENT.  Read an entry from the passwd file open on PASS.
/
/    code = get_ent (pass, name, passwd, line);
/   
/    Parameters:
/       int     code;     (return code)
/       FILE   *pass;     (open password file)
/       char   *name;     (returned userid)
/       char   *passwd;   (returned encrypted password)
/       char   *line;     (returned entire text line)
/
/    Purpose:
/       Read an entry from an NCSA-style "flat" password file,
/       and extract the userid and encrypted password fields.
/
/    How it works:
/       The password file must already be open on PASS.
/
/    Returns: 1 on success
/             0 on end-of-file.
