C#에서 C함수 사용하기

C함수 정의
extern unsigned int image_decode_header(const unsigned char *in, unsigned char *frames, unsigned char *bpp, unsigned short *width, unsigned short *height);

extern unsigned int image_decompress(const unsigned char *in, void *out);

extern int image_configure(const unsigned char *in, int start_x, int start_y, int lcd_type, int lcd_color);

C#함수 정의
[DllImport("lite_dll.lib")] static extern int image_configure([In] byte[] input, int start_x, int start_y, int lcd_type, int lcd_rotate , int lcd_color);
[DllImport("lite_dll.lib")] static extern int image_decode_header([In] byte[] input, ref byte frames, ref byte bpp, ref short width, ref short height);
[DllImport("lite_dll.lib")] static extern int image_decompress([In,Out] byte[] input, [In,Out] byte[] output);

아래는 사용법입니다.
image_configure(byImgArray , 0 , 0 , 0 , 0 , 0);
image_decode_header(byImgArray , ref rlsData.byFrame, ref rlsData.bitdepth , ref rlsData.width , ref rlsData.height);
image_decompress(byImgArray , rlsData.byRlsArray);
