c – Matlab Mex图书馆的生命周期

解决方法

@H_772_12@ 正如我在评论中提到的,在 Windows中可以实现 DllMain入口点.这是因为MEX文件只是具有不同扩展名的常规DLL文件.这是一个最小的例子：

testDLl.cpp

#include "mex.h"
#include <windows.h>

BOOL APIENTRY DllMain(HANDLE hModule,DWORD dwReason,LPVOID lpReserved)
{
    switch (dwReason) {
    case DLL_PROCESS_ATTACH:
        mexPrintf("DLL_PROCESS_ATTACH: hModule=0x%x\n",hModulE);
        break;
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
        break;
    case DLL_PROCESS_DETACH:
        mexPrintf("DLL_PROCESS_DETACH: hModule=0x%x\n",hModulE);
        break;
    }
    return TRUE;
}

void mexFunction(int nlhs,mxArray *plhs[],int nrhs,const mxArray *prhs[])
{
    mexPrintf("Inside MEX-function\n");
}

下面是它的工作原理：

>> mex -largeArrayDims testDLl.cpp

>> testDLL
DLL_PROCESS_ATTACH: hModule=0xa0980000
Inside MEX-function

>> testDLL
Inside MEX-function

>> clear testDLL
DLL_PROCESS_DETACH: hModule=0xa0980000
