NAME

       netinet/tcp.h - definitions for the Internet Transmission Control Protocol (TCP)

SYNOPSIS

       #include <netinet/tcp.h>

DESCRIPTION

       The <netinet/tcp.h> header shall define the following macro for use as a socket option at the IPPROTO_TCP level:

       TCP_NODELAY
	      Avoid coalescing of small segments.

       The macro shall be defined in the header. The implementation need not allow the value of the option to be set via setsockopt() or retrieved
       via getsockopt().

       The following sections are informative.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.

NAME

       assert.h - verify program assertion

SYNOPSIS

       #include <assert.h>

DESCRIPTION

       The  <assert.h>	header	shall  define  the assert() macro.  It refers to the macro NDEBUG which is not defined in the header. If NDEBUG is
       defined as a macro name before the inclusion of this header, the assert() macro shall be defined simply as:

	      #define assert(ignore)((void) 0)

       Otherwise, the macro behaves as described in assert().

       The assert() macro shall be redefined according to the current state of NDEBUG each time <assert.h> is included.

       The assert() macro shall be implemented as a macro, not as a function. If the macro definition is suppressed in order to access	an  actual
       function, the behavior is undefined.

       The following sections are informative.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
