DosWaitNmPipe

This call waits for the availability of a named pipe instance.

DosWaitNmPipe

(FileName, TimeOut)

FileName (PSZ) - input

Address of the ASCIIZ name of the pipe to be opened. Pipes are name \PIPE\FileName.
TimeOut (ULONG) - input
Maximum time in milliseconds to wait for the named pipe to become available. When a zero value is used, the DosMakeNmPipe specified default value is used. When a minus one value is used, an indefinite wait is entered.
rc (USHORT) - return
Return code descriptions are:
• NO_ERROR 2
  ERROR_FILE_NOT_FOUND
  95
  ERROR_INTERRUPT
  231
  ERROR_PIPE_BUSY
  Remarks

  This call should be used only when ERROR_PIPE_BUSY is returned from a DosOpen call.

  DosWaitNmPipe allows an application to wait for a server on a named pipe for which all instances are currently busy. The call waits up to TimeOut milliseconds (or a default time if TimeOut is zero).

  When a pipe instance becomes available, it is given to the process whose thread has the highest priority. The priority of a thread may be changed with DosSetPrty.
