- * Various and sundry Thread-Safe functions used by X11, Motif, and CDE.
- *
- * Use this file in MT-safe code where you would have included
- * <dirent.h> for readdir()
- * <grp.h> for getgrgid() or getgrnam()
- * <netdb.h> for gethostbyname(), gethostbyaddr(), or getservbyname()
- * <pwd.h> for getpwnam() or getpwuid()
- * <string.h> for strtok()
- * <time.h> for asctime(), ctime(), localtime(), or gmtime()
- * <unistd.h> for getlogin() or ttyname()
- * or their thread-safe analogs.
- *
- * If you are on a platform that defines XTHREADS but does not have
- * MT-safe system API (e.g. UnixWare) you must define _Xos_processLock
- * and _Xos_processUnlock macros before including this header. If
- * you are on OSF/1 V3.2 and plan to use readdir(), you must also define
- * _Xos_isThreadInitialized. For convenience XOS_USE_XLIB_LOCKING or
- * XOS_USE_XT_LOCKING may be defined to obtain either Xlib-only or
- * Xt-based versions of these macros. These macros won't result in
- * truly thread-safe calls, but they are better than nothing. If you
- * do not want locking in this situation define XOS_USE_NO_LOCKING.
- *
- * NOTE: On systems lacking appropriate _r functions Gethostbyname(),
- * Gethostbyaddr(), and Getservbyname() do NOT copy the host or
- * protocol lists!
- *
- * NOTE: On systems lacking appropriate _r functions Getgrgid() and
- * Getgrnam() do NOT copy the list of group members!
- *
- * This header is nominally intended to simplify porting X11, Motif, and
- * CDE; it may be useful to other people too. The structure below is
- * complicated, mostly because P1003.1c (the IEEE POSIX Threads spec)
- * went through lots of drafts, and some vendors shipped systems based
- * on draft API that were changed later. Unfortunately POSIX did not
- * provide a feature-test macro for distinguishing each of the drafts.
- */
- /*
- * This header has several parts. Search for "Effective prototypes"
- * to locate the beginning of a section.
