    1.18 +* FUNCTION
    1.19 +* <<assert>>---Macro for Debugging Diagnostics
    1.20 +* INDEX
    1.21 +* assert
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <assert.h>
    1.24 +* void assert(int <[expression]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <assert.h>
    1.27 +* assert(<[expression]>)
    1.28 +* int <[expression]>;
    1.29 +* Use this macro to embed debuggging diagnostic statements in
    1.30 +* your programs.  The argument <[expression]> should be an
    1.31 +* expression which evaluates to true (nonzero) when your program
    1.32 +* is working as you intended.
    1.33 +* When <[expression]> evaluates to false (zero), <<assert>>
    1.34 +* calls <<abort>>, after first printing a message showing what
    1.35 +* failed and where:
    1.36 +* . Assertion failed: <[expression]>, file <[filename]>, line <[lineno]>
    1.37 +* The macro is defined to permit you to turn off all uses of
    1.38 +* <<assert>> at compile time by defining <<NDEBUG>> as a
    1.39 +* preprocessor variable.   If you do this, the <<assert>> macro
    1.40 +* expands to
    1.41 +* . (void(0))
    1.42 +* RETURNS
    1.43 +* <<assert>> does not return a value.
    1.44 +* PORTABILITY
    1.45 +* The <<assert>> macro is required by ANSI, as is the behavior
    1.46 +* when <<NDEBUG>> is defined.
    1.47 +* Supporting OS subroutines required (only if enabled): <<close>>, <<fstat>>,
    1.48 +* <<getpid>>, <<isatty>>, <<kill>>, <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
