* Description:
* FUNCTION
* <<assert>>---Macro for Debugging Diagnostics
* INDEX
* assert
* ANSI_SYNOPSIS
* #include <assert.h>
* void assert(int <[expression]>);
* TRAD_SYNOPSIS
* #include <assert.h>
* assert(<[expression]>)
* int <[expression]>;
* Use this macro to embed debuggging diagnostic statements in
* your programs.  The argument <[expression]> should be an
* expression which evaluates to true (nonzero) when your program
* is working as you intended.
* When <[expression]> evaluates to false (zero), <<assert>>
* calls <<abort>>, after first printing a message showing what
* failed and where:
* . Assertion failed: <[expression]>, file <[filename]>, line <[lineno]>
* The macro is defined to permit you to turn off all uses of
* <<assert>> at compile time by defining <<NDEBUG>> as a
* preprocessor variable.   If you do this, the <<assert>> macro
* expands to
* . (void(0))
* RETURNS
* <<assert>> does not return a value.
* PORTABILITY
* The <<assert>> macro is required by ANSI, as is the behavior
* when <<NDEBUG>> is defined.
* Supporting OS subroutines required (only if enabled): <<close>>, <<fstat>>,
* <<getpid>>, <<isatty>>, <<kill>>, <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
