From cc29ad943903e9b8dba96cd978cb126f79f73e38 Mon Sep 17 00:00:00 2001 From: rpj Date: Tue, 2 Feb 1999 02:01:56 +0000 Subject: Mods to compile under Mingw32 egcs. Tue Feb 2 18:07:43 1999 Ross Johnson * implement.h: Add #include . Change sem_t to _pthread_sem_t. Various patches by Kevin Ruland * signal.c (pthread_sigmask): Add and modify casts. Reverse LHS/RHS bitwise assignments. * pthread.h: Remove #include . (_PTHREAD_ATTR_VALID): Add cast. (struct pthread_t_): Add sigmask element. * dll.c: Add "extern C" for DLLMain. (DllMain): Add cast. * create.c (pthread_create): Set sigmask in thread. * condvar.c: Remove #include. Change sem_* to _pthread_sem_*. * attr.c: Changed #include. * Makefile.in: Additional targets and changes to build the library as a DLL. Fri Jan 29 11:56:28 1999 Ross Johnson * Makefile.in (OBJS): Add semaphore.o to list. * semaphore.c (_pthread_sem_timedwait): Move from private.c. Rename sem_* to _pthread_sem_*. * pthread.h (pthread_cond_t): Change type of sem_t. _POSIX_SEMAPHORES no longer defined. * semaphore.h: Contents moved to implement.h. Removed from source tree. * implement.h: Add semaphore function prototypes and ename all functions to prepend '_pthread_'. They are now private to the pthreads-win32 implementation. * private.c: Change #warning. Move _pthread_sem_timedwait() to semaphore.c. * cleanup.c: Change #warning. * misc.c: Remove #include * pthread.def: Cleanup CVS merge conflicts. * global.c: Ditto. * ChangeLog: Ditto. * cleanup.c: Ditto. --- mutex.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'mutex.c') diff --git a/mutex.c b/mutex.c index 1a037f0..cca8fa3 100644 --- a/mutex.c +++ b/mutex.c @@ -42,20 +42,20 @@ _mutex_check_need_init(pthread_mutex_t *mutex) * the number of processors + 1. * * We need to maintain the following per-mutex state independently: - * - mutex staticinit (true iff static mutex and still + * - mutex staticinit (true iff mutex is static and still * needs to be initialised) * - mutex valid (false iff mutex has been destroyed) * - * For example, a mutex initialised by PTHREAD_MUTEX_INITIALIZER - * in this implementation will be valid but uninitialised until the thread - * attempts to lock it.
