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.

Member Typedef Documentation

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.

Definition at line 55 of file kcrash.h.


Member Function Documentation

static HandlerType TDECrash::crashHandler (  )  [inline, static]

Returns the installed crash handler.

Returns:
the crash handler

Definition at line 74 of file kcrash.h.

void TDECrash::defaultCrashHandler ( int  signal  )  [static]

The default crash handler.

Parameters:
signal the signal number

Definition at line 119 of file kcrash.cpp.

static HandlerType TDECrash::emergencySaveFunction (  )  [inline, static]

Return the currently set emergency save function.

Returns:
the emergency save function

Definition at line 88 of file kcrash.h.

static void TDECrash::setApplicationName ( TQString  name  )  [inline, static]

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 kcrash.h.

static void TDECrash::setApplicationPath ( TQString  path  )  [inline, static]

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 kcrash.h.

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 kcrash.cpp.

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 kcrash.cpp.

static void TDECrash::setSafer ( bool  on  )  [inline, static]

Set whether to start drkonqi without arbitrary disk access.

Definition at line 93 of file kcrash.h.

Definition at line 115 of file kcrash.h.

TDECrash::HandlerType TDECrash::_emergencySaveFunction = 0 [static, protected]

Pointer to the emergency save function.

Definition at line 119 of file kcrash.h.
