VxWorks6创建RTP例程.docVIP

. VxWorks6.6动态创建RTP例程? VxWorks6.6中的RTP程序与WINDOWS的exe程序类似，我们可以使用操作系统的进程创建函数API，在程序中动态创建和调用。下面主要通过Download Kernel moudle来测试该API使用，整个调试过程与Tornado2.2基本相似，具体操作流程如下面描述。 1、创建Downloadable Kernel module工程 2、新建main.cpp文件 3、main.cpp代码如下 [cpp] view plaincopyprint? #include?vxWorks.h?? #include?stdio.h?? #include?rtpLibCommon.h?? #include?errnoLib.h?? #include?usrLib.h?? ?? int?main?(void)?? {?? ????int?nRtp;?? ????//?注意这里的文件路径使用虚拟路径，否则将出现nRtp=-1不成功的状态！?? ????const?char?*argv[]?=?{/C/openSUSE3000/fep/bin/testdemo.vxe,?NULL};?? ????const?char?*envp[]?=?{HEAP_INITIAL_SIZE=0x20000,?HEAP_MAX_SIZE=0x100000,?NULL};?? ????nRtp?=?(int)rtpSpawn(argv[0],?argv,?envp,?100,?0x10000,?0,?0);?? ????if?(nRtp?==?-1)?? ????{?? ????????printErrno(errnoGet());?? ????????printf?(The?RTP?task?not?spawned!\n);?? ????}?? ????else?? ????{?? ????????printf?(This?is?a?task?spawned?by?testvxe?program!\n);?? ????}?? ????return?0;?? }?? #include vxWorks.h #include stdio.h #include rtpLibCommon.h #include errnoLib.h #include usrLib.h int main (void) { int nRtp; // 注意这里的文件路径使用虚拟路径，否则将出现nRtp=-1不成功的状态！ const char *argv[] = {/C/openSUSE3000/fep/bin/testdemo.vxe, NULL}; const char *envp[] = {HEAP_INITIAL_SIZE=0x20000, HEAP_MAX_SIZE=0x100000, NULL}; nRtp = (int)rtpSpawn(argv[0], argv, envp, 100, 0x10000, 0, 0); if (nRtp == -1) { printErrno(errnoGet()); printf (The RTP task not spawned!\n); } else { printf (This is a task spawned by testvxe program!\n); } return 0; } 4、编译工程 Build Started in Project testvxe:?? 2011-09-23 17:05:40 Generation of makefiles started.
