Detailed Description

This class handles segmentation-faults.

By default it displays a message-box saying the application crashed. This default can be overridden by setting a custom crash handler with setCrashHandler(). If a function is specified with setEmergencySaveFunction() it will be called by the default crash handler, giving the application a chance to save its data.

typedef void(* TDECrash::HandlerType) (int)

This function type is a pointer to a crash handler function.

The function's argument is the number of the signal.

Member Function Documentation

crashHandler()

static HandlerType TDECrash::crashHandler ( )

inlinestatic

Returns the installed crash handler.

Returns

the crash handler

Definition at line 74 of file tdecrash.h.

defaultCrashHandler()

void TDECrash::defaultCrashHandler ( int  signal )

static

The default crash handler.

Parameters

signal

the signal number

Definition at line 119 of file tdecrash.cpp.

emergencySaveFunction()

static HandlerType TDECrash::emergencySaveFunction ( )

inlinestatic

Return the currently set emergency save function.

Returns

the emergency save function

Definition at line 88 of file tdecrash.h.

setApplicationName()

static void TDECrash::setApplicationName ( TQString  name )

inlinestatic

Sets the application name name which should be passed to Dr.

Konqi, our nice crash display application.

Parameters

name	the name of the application, as shown in Dr. Konqi

Definition at line 108 of file tdecrash.h.

setApplicationPath()

static void TDECrash::setApplicationPath ( TQString  path )

inlinestatic

Sets the application path which should be passed to Dr.

Konqi, our nice crash display application.

Parameters

path	the application path.

Definition at line 100 of file tdecrash.h.

setCrashHandler()

void TDECrash::setCrashHandler ( HandlerType  handler = defaultCrashHandler )

static

Install a function to be called in case a SIGSEGV is caught.

Parameters

handler	HandlerType handler can be one of null in which case signal-catching is disabled (by calling signal(SIGSEGV, SIG_DFL)) if handler is omitted the default crash handler is installed. an user defined function in the form: static (if in a class) void myCrashHandler(int);
handler	the crash handler

Definition at line 86 of file tdecrash.cpp.

setEmergencySaveFunction()

void TDECrash::setEmergencySaveFunction ( HandlerType  saveFunction = (HandlerType)0 )

static

Installs a function which should try to save the applications data.

It is the crash handler´s responsibility to call this function. Therefore, if no crash handler is set, the default crash handler is installed to ensure the save function is called.

Parameters

saveFunction

the handler to install

Definition at line 70 of file tdecrash.cpp.

setSafer()

static void TDECrash::setSafer ( bool  on )

inlinestatic

Set whether to start drkonqi without arbitrary disk access.

Definition at line 93 of file tdecrash.h.
