Contains: This file defines structured error handling and assertion macros for
|
|||
|
|
programming in C. Originally used in QuickDraw GX and later enhanced.
|
|||
|
|
These macros are used throughout Apple's software.
|
|||

/*
|
|||
|
|
* Macro overview:
|
|||
|
|
*
|
|||
|
|
* check(assertion)
|
|||
|
|
* In production builds, pre-processed away
|
|||
|
|
* In debug builds, if assertion evaluates to false, calls DEBUG_ASSERT_MESSAGE
|
|||
|
|
*
|
|||
|
|
* verify(assertion)
|
|||
|
|
* In production builds, evaluates assertion and does nothing
|
|||
|
|
* In debug builds, if assertion evaluates to false, calls DEBUG_ASSERT_MESSAGE
|
|||
|
|
*
|
|||
|
|
* require(assertion, exceptionLabel)
|
|||
|
|
* In production builds, if the assertion expression evaluates to false, goto exceptionLabel
|
|||
|
|
* In debug builds, if the assertion expression evaluates to false, calls DEBUG_ASSERT_MESSAGE
|
|||
|
|
* and jumps to exceptionLabel
|
|||
|
|
*
|
|||
|
|
* In addition the following suffixes are available:
|
|||
|
|
*
|
|||
|
|
* _noerr Adds "!= 0" to assertion. Useful for asserting and OSStatus or OSErr is noErr (zero)
|
|||
|
|
* _action Adds statement to be executued if assertion fails
|
|||
|
|
* _quiet Suppress call to DEBUG_ASSERT_MESSAGE
|
|||
|
|
* _string Allows you to add explanitory message to DEBUG_ASSERT_MESSAGE
|
|||
|
|
*
|
|||
|
|
* For instance, require_noerr_string(resultCode, label, msg) will do nothing if
|
|||
|
|
* resultCode is zero, otherwise it will call DEBUG_ASSERT_MESSAGE with msg
|
|||
|
|
* and jump to label.
|
|||
|
|
*
|
|||
|
|
* Configuration:
|
|||
|
|
*
|
|||
|
|
* By default all macros generate "production code" (i.e non-debug). If
|
|||
|
|
* DEBUG_ASSERT_PRODUCTION_CODE is defined to zero or DEBUG is defined to non-zero
|
|||
|
|
* while this header is included, the macros will generated debug code.
|
|||
|
|
*
|
|||
|
|
* If DEBUG_ASSERT_COMPONENT_NAME_STRING is defined, all debug messages will
|
|||
|
|
* be prefixed with it.
|
|||
|
|
*
|
|||
|
|
* By default, all messages write to stderr. If you would like to write a custom
|
|||
|
|
* error message formater, defined DEBUG_ASSERT_MESSAGE to your function name.
|
|||

* DEBUG_ASSERT_MESSAGE()
|
|||
|
|
*
|

|
|
* Summary:
|
|||
|
|
* All assertion messages are routed through this macro. If you wish to use your
|
|||
|
|
* own routine to display assertion messages, you can override DEBUG_ASSERT_MESSAGE
|
|||
|
|
* by #defining DEBUG_ASSERT_MESSAGE before including this file.
|
|||
|
|
*
|
|||
|
|
* Parameters:
|
|||
|
|
*
|
|||
|
|
* componentNameString:
|
|||
|
|
* A pointer to a string constant containing the name of the
|
|||
|
|
* component this code is part of. This must be a string constant
|
|||
|
|
* (and not a string variable or NULL) because the preprocessor
|
|||
|
|
* concatenates it with other string constants.
|
|||
|
|
*
|
|||
|
|
* assertionString:
|
|||
|
|
* A pointer to a string constant containing the assertion.
|
|||
|
|
* This must be a string constant (and not a string variable or
|
|||
|
|
* NULL) because the Preprocessor concatenates it with other
|
|||
|
|
* string constants.
|
|||
|
|
*
|
|||
|
|
* exceptionLabelString:
|
|||
|
|
* A pointer to a string containing the exceptionLabel, or NULL.
|
|||
|
|
*
|
|||
|
|
* errorString:
|
|||
|
|
* A pointer to the error string, or NULL. DEBUG_ASSERT_MESSAGE macros
|
|||
|
|
* must not attempt to concatenate this string with constant
|
|||
|
|
* character strings.
|
|||
|
|
*
|
|||
|
|
* fileName:
|
|||
|
|
* A pointer to the fileName or pathname (generated by the
|
|||
|
|
* preprocessor __FILE__ identifier), or NULL.
|
|||
|
|
*
|
|||
|
|
* lineNumber:
|
|||
|
|
* The line number in the file (generated by the preprocessor
|
|||
|
|
* __LINE__ identifier), or 0 (zero).
|
|||
|
|
*
|
|||
|
|
* errorCode:
|
|||
|
|
* A value associated with the assertion, or 0.
|
|||
|
|
*
|
|||
|
|
* Here is an example of a DEBUG_ASSERT_MESSAGE macro and a routine which displays
|
|||
|
|
* assertion messsages:

|||
|
|
*
|
|||
|
|
* #define DEBUG_ASSERT_COMPONENT_NAME_STRING "MyCoolProgram"
|
|||
|
|
*

* #define DEBUG_ASSERT_MESSAGE(componentNameString, assertionString, \
|

|
|||
|
|
* MyProgramDebugAssert(componentNameString, assertionString, \
|
|||
|
|
* exceptionLabelString, errorString, fileName, lineNumber, errorCode)
|
|||
|
|
*
|
|||
|
|
* static void
|

|
|||
|
|
* const char *exceptionLabelString, const char *errorString,
|
|||
|
|
* const char *fileName, long lineNumber, int errorCode)
|
|||
|
|
* {
|
|||
|
|
* if ( (assertionString != NULL) && (*assertionString != \'0') )
|
|||
|
|
* fprintf(stderr, "Assertion failed: %s: %s\n", componentNameString, assertionString);
|
|||
|
|
* else
|
|||

* fprintf(stderr, "Check failed: %s:\n", componentNameString);
|
|||
|

* if ( errorString != NULL )
|
|||
|
|
* fprintf(stderr, " %s\n", errorString);
|
|||
|
|
* if ( fileName != NULL )
|
|||
|
|
* fprintf(stderr, " file: %s\n", fileName);
|
|||
|
|
* if ( lineNumber != 0 )
|
|||
|
|
* fprintf(stderr, " line: %ld\n", lineNumber);
|
|||
|
|
* if ( errorCode != 0 )
|
|||
|
|
* fprintf(stderr, " error: %d\n", errorCode);
|
|||
|
|
* }
|
|||
|
|
*
|
|||
|
|
* If you do not define DEBUG_ASSERT_MESSAGE, a simple printf to stderr will be used.
