RasEnumDevices

This function returns the name and type of all available RAS-capable devices.

DWORD RasEnumDevices( 
  LPRASDEVINFOW lpRasDevinfo, 
  LPDWORD lpcb, 
  LPDWORD lpcDevices 
);

lpRasDevinfo
Long pointer to a buffer that receives an array of RASDEVINFO structures, one for each RAS-capable device. Before calling the function, set the dwSize member of the first RASDEVINFO structure in the buffer to sizeof(RASDEVINFO) to identify the version of the structure.
lpcb
Long pointer to a variable that contains the size, in bytes, of the lpRasDevInfo buffer. On return, the function sets this variable to the number of bytes required to enumerate the devices.
lpcDevices
Long pointer to a variable that the function sets to the number of RASDEVINFO structures written to the lpRasDevinfo buffer.

Zero indicates success. A nonzero error value indicates failure. Valid error codes (as defined in Raserror.h) include: ERROR_BUFFER_TOO_SMALL.
