int SDF_ReadFile(void *hSessionHandle, unsigned char *pucFileName, unsigned int uiNameLen, unsigned int uiOffset, unsigned int *puiFileLength, unsigned char *pucBuffer);
int SDF_WriteFile(void *hSessionHandle, unsigned char *pucFileName, unsigned int uiNameLen, unsigned int uiOffset, unsigned int uiFileLength, unsigned char *pucBuffer);
int SDF_DeleteFile(void *hSessionHandle, unsigned char *pucFileName, unsigned int uiNameLen);
