    MATLAB error

    I got this crazy error out of my matlab code and i know you guys dont know matlab nessasarily but i have bolded the interesting part. I was just wondering if you had any insight.

    what i did was link to DTEST.dll
    I inlcuded the header DLLTEST.h seen here:
    #include "niimaq.h"
    #include "stdint.h"
    // Error display function
    extern "C" __declspec(dllexport) void DisplayIMAQError(int32_t error);
    // Callbacks
    extern "C" __declspec(dllexport) int AnalogueCardInit(uint32_t *Sid, uint32_t *Iid, uint8_t *image1D, uint8_t **image2D);
    extern "C" __declspec(dllexport) int AnalogueCardClose(uint32_t *Sid, uint32_t *Iid);
    extern "C" __declspec(dllexport) int AnalogueCardSnap(uint32_t Sid, uint8_t *ImaqBuffer, uint32_t top, uint32_t left, uint32_t height, uint32_t width);
    i also inlcuded (just like #inlcude) stdint.h and another header which has the prototypes for another library DTEST.dll links to:

    USER_FUNC imgInterfaceOpen(const int8_t* interface_name, uint32_t* ifid);
    USER_FUNC imgSessionOpen(uint32_t ifid, uint32_t* sid);
    USER_FUNC imgClose(uint32_t void_id, uint32_t freeResources);
    USER_FUNC imgSnap(uint32_t sid, void **bufAddr);
    USER_FUNC imgSnapArea(uint32_t sid, void **bufAddr,uint32_t top,uint32_t left, uint32_t height, uint32_t width,uint32_t rowBytes);
    USER_FUNC imgGrabSetup(uint32_t sid, uint32_t startNow);
    USER_FUNC imgGrab(uint32_t sid, void** bufPtr, uint32_t syncOnVB);
    USER_FUNC imgGrabArea(uint32_t sid, void** bufPtr, uint32_t syncOnVB, uint32_t top, uint32_t left, uint32_t height, uint32_t width, uint32_t rowBytes);
    USER_FUNC imgRingSetup(uint32_t sid,  uint32_t numberBuffer,void* bufferList[], uint32_t skipCount, uint32_t startnow);
    USER_FUNC imgSequenceSetup(uint32_t sid,  uint32_t numberBuffer,void* bufferList[], uint32_t skipCount[], uint32_t startnow, uint32_t async);
    USER_FUNC imgSessionStartAcquisition(uint32_t sid);
    USER_FUNC imgSessionStopAcquisition(uint32_t sid);
    USER_FUNC imgSessionStatus(uint32_t sid, uint32_t* boardStatus, uint32_t* bufIndex);
    USER_FUNC imgSessionConfigureROI(uint32_t sid, uint32_t top, uint32_t left, uint32_t height, uint32_t width);
    USER_FUNC imgSessionGetROI(uint32_t sid, uint32_t* top, uint32_t* left, uint32_t* height, uint32_t* width);
    USER_FUNC imgSessionGetBufferSize(uint32_t sid, uint32_t* sizeNeeded);
    USER_FUNC imgGetAttribute(uint32_t void_id, uint32_t type, void* value);
    USER_FUNC imgCreateBuffer(uint32_t sid, uint32_t where, uint32_t bufferSize, void** bufAddr);
    USER_FUNC imgDisposeBuffer(void* bufferPtr);
    USER_FUNC imgShowError(uint32_t error, int8_t* text);

    Is the above what line 59 looks like in stdint.h?
