Hi,
I've been trying to make few wrapper functions so that I could build
code written for FTDI's FT2XX library.
Now I got the program to work but I'm just wondering if I'm doing
things right here. In the following code I
had to add the while loop to make it work.
FTD2XX_API FT_STATUS WINAPI FT_Read(FT_HANDLE ftHandle, LPVOID
lpBuffer, DWORD dwBytesToRead, LPDWORD lpBytesReturned)
{
ftdi_context *ftdi = NULL;
int ret = 0;
ftdi = (ftdi_context *)ftHandle;
while ((ret = ftdi_read_data(ftdi, (unsigned char *)lpBuffer,
dwBytesToRead)) == 0);
if (ret < 0)
{
fprintf(stderr,"ftdi_read_data failed: %d (%s)\n", ret,
ftdi_get_error_string(ftdi));
return EXIT_FAILURE;
}
*lpBytesReturned = ret;
return 0;
}
Also I haven't yet figured out how to implement FT_GetQueueStatus, but
it seems that I could live without
it by using #ifdef to get rid of it when compiling the code for Linux.
