+ * setpwent Reset search to the start of the rights database
+ * endpwent Finish searching for users in the rights database
+ *
+ * getpwuid, getpwnam, and getpwent return a pointer to the passwd structure

+ * char *pw_name; Username (in lower case)
+ * char *pw_passwd; Hashed password
+ * unsigned int pw_uid; UIC
+ * unsigned int pw_gid; UIC group number
+ * char *pw_unixdir; Default device/directory (VMS-style)

+ * char *pw_shell; Default CLI name (eg. DCL)

+ * If the specified user does not exist, getpwuid and getpwnam return NULL.
+ *
+ * pw_uid is the full UIC (eg. what's returned by stat() in st_uid).
+ * not the UIC member number (eg. what's returned by getuid()),
+ * getpwuid() can accept either as input (if uid is specified, the caller's
+ * UIC group is used), though it won't recognise gid=0.
