NAME
nng_pipe_id - return numeric pipe identifier
SYNOPSIS
DESCRIPTION
The nng_pipe_id() function returns a positive identifier for the pipe p,
if it is valid.
Otherwise it returns -1.
A pipe is considered valid if it was ever created by the socket.
Pipes that are allocated on the stack or statically should be
initialized with the macro
NNG_PIPE_INITIALIZER to ensure that
they cannot be confused with a valid pipe.
|
RETURN VALUES
This function returns the positive value for the pipe identifier, or
-1 if the pipe is invalid.
ERRORS
None.
