Applications should assume that the native dlopen is NOT thread-safe, and take care of locking themselves. All application calls into libltdl should thus be protected by the caller. * libltdl/lt_mutex.c, libltdl/lt_mutex.h: Removed. * libltdl/Makefile.am (pkginclude_HEADERS): Removed lt_mutex.h. (libltdl_la_SOURCES): Removed lt_mutex.c and lt_mutex.h. * libltdl/ltdl.h: Don't include lt_mutex.h. * libltdl/lt__private.h (LT__MUTEX_GETERROR, LT__MUTEX_SETERROR) (LT__MUTEX_SETERRORSTR): Renamed to... (LT__GETERROR, LT__SETERROR, LT__SETERRORSTR): ...this. Changed all callers. (LT__MUTEX_LOCK, LT__MUTEX_UNLOCK, lt_dlmutex_lock) (lt_dlmutex_unlock, lt_dlmutex_seterror, lt_dlmutex_geterror): Removed. Changed all callers. * doc/libtool.texi (Thread Saftey in libltdl): * NEWS: Updated.
