DosQueryNPipeInfo returns all of the level-1 or level-2 information about a named pipe that will fit in the pBuf storage area.

If the length of the pipe name is greater than 255 bytes, then a length of 0 is returned in the namelength field; however, the full ASCIIZ name is still returned in the pipename field.

If there is more information than will fit in pBuf ERROR_BUFFER_OVERFLOW is returned.
