C_SaveDiffractionResultsMem

Call C_SaveDiffractionResultsMem to save OrcaWave results to memory.

void C_SaveDiffractionResultsMem(

TOrcFxAPIHandle DiffractionHandle,

TOrcFxAPIHandle *lpBufferHandle,

int64_t *lpBufferLen,

int *lpStatus

);

Parameters

DiffractionHandle (IN)

The diffraction handle returned by C_CreateDiffraction.

lpBufferHandle (OUT)

Points to a variable in which a handle to the saved buffer will be returned.

lpBufferLen (OUT)

Points to a variable in which the length of the saved buffer will be returned.

lpStatus (OUT)

Points to a variable in which the status result for the function call will be returned.

Remarks

In order to extract the contents of the buffer, you must follow the call to C_SaveDiffractionResultsMem with calls to C_CopyBuffer and C_FreeBuffer. Use the value returned in lpBufferLen to allocate a suitably sized buffer. Pass this to C_CopyBuffer to perform the copy. Finally, call C_FreeBuffer to free the buffer handle.

Such code typically looks like this:

TOrcFxAPIHandle BufferHandle;

int64_t BufferLen;

int Status;

C_SaveDiffractionResultsMem(DiffractionHandle, &BufferHandle, &BufferLen, &Status);

unsigned char *lpBuffer = new unsigned char[BufferLen];

C_CopyBuffer(BufferHandle, lpBuffer, BufferLen, &Status);

C_FreeBuffer(BufferHandle, &Status);

// use lpBuffer

delete[] lpBuffer;

Note that, for the sake of brevity, error checking has been omitted from the above code.
