ND_NODE_CMP()

Compare two node descriptors

Synopsis:

#include <sys/netmgr.h>

#define ND_NODE_CMP(a,b) ...

Arguments:

a, b

The node descriptors that you want to compare. You can use either the value 0 or ND_LOCAL_NODE to refer to the local node.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The ND_NODE_CMP() macro compares two node descriptors.

Returns:

< 0

The node descriptor a is less than b.

0

The descriptors refer to the same machine.

> 0

The node descriptor a is greater than b.

Examples:

#include <sys/neutrino.h>

uint32_t nd1, nd2;

if ( ND_NODE_CMP(nd1, nd2) == 0 ) {
  /* Same node */
  ...
} else {
  /* Different nodes */
  ...
}

Classification:

QNX Neutrino

Safety:
Cancellation point	No
Interrupt handler	Yes
Signal handler	Yes
Thread	Yes
