- * 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.
- *
- * 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.

+ * 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()

+ * 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.
+ *
+ * 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.
