Library: Foundation
Package: Core
Header: Poco/Debugger.h

## Description

The Debugger class provides an interface to the debugger. The presence of a debugger can be checked for, messages can be written to the debugger's log window and a break into the debugger can be enforced. The methods only work if the program is compiled in debug mode (the macro _DEBUG is defined).

## Member Summary

Member Functions: enter, isAvailable, message

## Member Functions

### enter

static void enter();

Breaks into the debugger, if it is available. On Windows, this is done using the DebugBreak() function. On Unix, the SIGINT signal is raised.

### enter

static void enter(
const std::string & msg
);

Writes a debug message to the debugger log and breaks into it.

### enter

static void enter(
const std::string & msg,
const char * file,
int line
);

Writes a debug message to the debugger log and breaks into it.

### enter

static void enter(
const char * file,
int line
);

Writes a debug message to the debugger log and breaks into it.

### isAvailable

static bool isAvailable();

Returns true if a debugger is available, false otherwise. On Windows, this function uses the IsDebuggerPresent() function. On Unix, this function returns true if the environment variable POCO_ENABLE_DEBUGGER is set.

### message

static void message(
const std::string & msg
);

Writes a message to the debugger log, if available, otherwise to standard error output.

### message

static void message(
const std::string & msg,
const char * file,
int line
);

Writes a message to the debugger log, if available, otherwise to standard error output.
