Thread: error C2664: cannot convert parameter 1 from float** __w64 to float *

Hi,

simply put the following code generates the error

Code:

error C2664: 'vGetPixelValueIntoArray' : cannot convert parameter 1 from 'float **__w64  ' to 'float *'

Code:

int main(int argc, char **argv) {
   
float **ppfImageData;/* a pointer to a series of 2d arrays */
s_Filename *psFile;
s_Header *psHeader;
	
psFile = (struct s_Filename *) malloc(sizeof(s_Filename));
psHeader = (struct s_Header *) malloc(sizeof(s_Header));

if (argc < 2){strncpy(acFilename, "C:\\Documents and Settings\\matt smith\\Desktop\\example\\img0061.ppm", sizeof(acFilename));}
else {strncpy(acFilename,argv[1],sizeof(acFilename));}

psFile = psGetImageBase(acFilename, psFile); //not important
psHeader = psGetHeader(psFile->acNextFileName, psHeader); //not important

psHeader->nPhotosToBeCounted = psFile->nMaxImagenumber;

	if(!(ppfImageData = (float **) malloc(psHeader->nPhotosToBeCounted))){
        fprintf(stderr, "Failed to allocate memory for imageMatrix array!\n");
		return NULL;
	}

vGetPixelValueIntoArray(&ppfImageData[nCountI], psFile->acNextFileName, psHeader); //this is the line that causes the error (the &ppfImageData is the problem variable)

}

void vGetPixelValueIntoArray(float *pfImageData, const char* pccFilename, s_Header* psHeader ) {// returns NULL if error 
    size_t nCounter, nSecondCounter;
    FILE *pFTemp_file;

	psHeader->nWantedPixels = 5;

	if (!(pfImageData = (float *) malloc(psHeader->nWantedPixels))){ //malloc array for image data
        fprintf(stderr, "Failed to allocate memory in *pfGetPixelValueIntoArray");
        exit(-1);
    }	
}

I have looked into this problem and it could be a win32 problem but I have tried all of the suggestions about pre-processing I could find, was wondering if anyone had any ideas where I was going wrong...
