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