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

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

Parameters

  • 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.
