+== NAME
+
+nng_pipe_id - return numeric pipe identifier
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nng/nng.h>
+
+int nng_pipe_id(nng_pipe p);
+----
+
+== DESCRIPTION
+
+The `nng_pipe_id()` function returns a positive identifier for the pipe _p_,
+if it is valid.
+Otherwise it returns `-1`.
+
+NOTE: A pipe is considered valid if it was ever opened with
+<<nng_pipe_open.3#,`nng_pipe_open`>> function.
+Pipes that are allocated on the stack or statically should be
+initialized with the macro
+<<nng_pipe.5#NNG_PIPE_INITIALIZER,`NNG_PIPE_INITIALIZER`>> to ensure that
+they cannot be confused with a valid pipe before they are opened.
+
+== RETURN VALUES
+
+This function returns the positive value for the pipe identifier, or
+`-1` if the pipe is invalid.
+
+== ERRORS
+
+None.
+
+== SEE ALSO

+<<nng_pipe.5#,nng_pipe(5)>>,
+<<nng.7#,nng(7)>>
