THFACELIVE_API void THFL_SDK_SetDir(const char* modelDir, const char* tmpDir);
/*
 The THFL_SDK_SetDir function will set SDK environment directory,it must be called before THFL_Create
 Parameters:
	modelDir[input],存放 libTHFacelive_*.so文件的目录，如果modelDir为NULL，则使用libTHFaceLive.so所在的目录
	tmpDir[input],临时读写目录，供算法初始化使用，算法必须具有临时目录下的读写权限,如果tmpDir为NULL，则使用默认路径"/tmp/"		
 Return Values:
	No return value.
 Remarks：         
	It must be called before THFL_Create.

The THFL_Create function will initialize the algorithm engine module

Parameters:
	nChannelNum[intput],algorithm channel num,for multi-thread mode,one thread uses one channel
Return Values:
	If the function succeeds, the return value is valid channel number.
	If the function fails, the return value is negative;
Remarks:
	This function only can be called one time at program initialization.

The THFL_Release function will release the algorithm engine module

Parameters:
	No parameter.
Return Values:
	No return value.
Remarks:
	This function only can be called one time at program exit.

The THFL_Detect function execute face liveness detection

Parameters:
	nChannelID[input],channel ID(from 0 to nChannelNum-1)
	pBuf_color[input],color camera image data buffer,BGR format.
	pBuf_bw[input],black-white camera image data buffer,BGR format.
	nWidth[input],image width.
	nHeight[input],image height.
	ptfp_color[input],face data of color camera image.(THFI_FacePos format,return by THFI_DetectFace of THFaceImage SDK)
	ptfp_bw[input],face data of black-white camera image.(THFI_FacePos format,return by THFI_DetectFace of THFaceImage SDK)
	nThreshold[input],score threshold(sugguest value is 50)
Return Values:
	If the function succeeds, the return value is 0 or 1.(0->fake face,1->live face)
	If the function fails, the return value is negative.
Remarks:

The THFL_Create_Ex function will initialize the algorithm engine module with openmp thread num

Parameters:
	nChannelNum[intput],algorithm channel num,for multi-thread mode,one thread uses one channel
	omp_thread_num[input],thread num for openmp
Return Values:
	If the function succeeds, the return value is valid channel number.
	If the function fails, the return value is zero or negative;
error code:
