ansiAssert

NAME

ansiAssert - ANSI assert documentation

ROUTINES

assert( ) - put diagnostics into programs (ANSI)

DESCRIPTION

The header assert.h defines the assert( ) macro and refers to another macro, NDEBUG, which is not defined by assert.h. If NDEBUG is defined as a macro at the point in the source file where assert.h is included, the assert( ) macro is defined simply as:

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

ANSI specifies that assert( ) should be implemented as a macro, not as a routine. If the macro definition is suppressed in order to access an actual routine, the behavior is undefined.

stdio.h, stdlib.h, assert.h

assert( )

NAME

assert( ) - put diagnostics into programs (ANSI)

SYNOPSIS

void assert
    (
    int a
    )

DESCRIPTION

If an expression is false (that is, equal to zero), the assert( ) macro writes information about the failed call to standard error in an implementation-defined format. It then calls abort( ). The diagnostic information includes:
    - the text of the argument
    - the name of the source file (value of preprocessor macro __FILE__)
    - the source line number (value of preprocessor macro __LINE__)

INCLUDE

stdio.h, stdlib.h, assert.h

RETURNS

N/A
