From c4f585589ab715ef1aa3c4ab01cffeff2fc69ea9 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Thu, 18 Jul 2013 14:14:04 +0200 Subject: score: Create semaphore implementation header Move implementation specific parts of coresem.h and coresem.inl into new header file coresemimpl.h. The coresem.h contains now only the application visible API. --- cpukit/score/inline/rtems/score/coresem.inl | 118 ---------------------------- 1 file changed, 118 deletions(-) delete mode 100644 cpukit/score/inline/rtems/score/coresem.inl (limited to 'cpukit/score/inline/rtems/score') diff --git a/cpukit/score/inline/rtems/score/coresem.inl b/cpukit/score/inline/rtems/score/coresem.inl deleted file mode 100644 index 0ae3b33cd3..0000000000 --- a/cpukit/score/inline/rtems/score/coresem.inl +++ /dev/null @@ -1,118 +0,0 @@ -/** - * @file - * - * @brief Inlined Routines Associated with the SuperCore Semaphore - * - * This include file contains all of the inlined routines associated - * with the SuperCore semaphore. - */ - -/* - * COPYRIGHT (c) 1989-2006. - * On-Line Applications Research Corporation (OAR). - * - * The license and distribution terms for this file may be - * found in the file LICENSE in this distribution or at - * http://www.rtems.com/license/LICENSE. - */ - -#ifndef _RTEMS_SCORE_CORESEM_H -# error "Never use directly; include instead." -#endif - -#ifndef _RTEMS_SCORE_CORESEM_INL -#define _RTEMS_SCORE_CORESEM_INL - -/** - * @addtogroup ScoreSemaphore - */ -/**@{**/ - -#include -#include -#include - -/** - * This function returns true if the priority attribute is - * enabled in the @a attribute_set and false otherwise. - * - * @param[in] the_attribute is the attribute set to test - * - * @return true if the priority attribute is enabled - */ -RTEMS_INLINE_ROUTINE bool _CORE_semaphore_Is_priority( - CORE_semaphore_Attributes *the_attribute -) -{ - return ( the_attribute->discipline == CORE_SEMAPHORE_DISCIPLINES_PRIORITY ); -} - -/** - * This routine returns the current count associated with the semaphore. - * - * @param[in] the_semaphore is the semaphore to obtain the count of - * - * @return the current count of this semaphore - */ -RTEMS_INLINE_ROUTINE uint32_t _CORE_semaphore_Get_count( - CORE_semaphore_Control *the_semaphore -) -{ - return the_semaphore->count; -} - -/** - * This routine attempts to receive a unit from the_semaphore. - * If a unit is available or if the wait flag is false, then the routine - * returns.
