// Description of module ToolSignal
// --------------------------------
// This module does all the standard signal handling work for an application. When catching a standard
// signal (Kill, Hup, Break...) it calls the function that has been indicated in param pFnLog.
// If ever a segment violation occurs, a stack trace is done in order to log the function call sequence
// before exiting the program.
//
// All logging is done via the function indicated in param pFnLog. If that one is NULL, the module writes
// its log outputs to stdout. Its first parameter (Error) indicates whether a normal log output (info) or
// whether an error log entry should be done.
//
// It might be important to know for the application, that ToolSignalInit starts a new thread. The function
// indicated in param pFnSig is called from that thread, if pFnSig is not NULL. The ID of the new thread is
// written to where pThreadId points, if pThreadId is not NULL.

typedef void (* t_pToolSignalLogFn  )(bool Error, int ThreadNr, const char *pFileName, const char *pFunction, int LineNr, const char *pFormat, va_list pArguments);
typedef void (* t_pToolSignalHandler)(int Signal);

int ToolSignalInit   (t_pToolSignalLogFn pFnLog, t_pToolSignalHandler pFnSig, int *pThreadId);
