Function Documentation

void MeDebug ( int level, const char * const format, ... )

The debug message function.

Calls a message handler, and the default ones will then call a message print function.

Parameters:

level	The level of the message.
format	A printf style format string.
...	The list of parameters for the format string.

void MeFatalError ( int level, const char * const format, ... )

The fatal error message function.

Calls a message handler, and the default ones will then call a message print function. It will then by default abort the program.

Parameters:

level	The level of the message.
format	A printf style format string.
...	The list of parameters for the format string.

void MeHandlerDebug ( int level, const char * const format, va_list ap )

Default handler for fatal error messages.

Does nothing if the level of the message is greater than the current information message level. Otherwise formats it and prints it using *MeDebugShow.

void MeHandlerFatalError ( int level, const char * const format, va_list ap )

Default handler for fatal error messages.

Does nothing if the level of the message is greater than the current information message level. Otherwise formats it and prints it using *MeFatalErrorShow, and then aborts the program.

void MeHandlerInfo ( int level, const char * const format, va_list ap )

Default handler for information messages.

Does nothing if the level of the message is greater than the current information message level. Otherwise formats it and prints it using *MeInfoShow.

void MeHandlerWarning ( int level, const char * const format, va_list ap )

Default handler for warning messages.

Does nothing if the level of the message is greater than the current information message level. Otherwise formats it and prints it using *MeWarningShow.

void MeInfo ( int level, const char * const format, ... )

The informational message function.

Calls a message handler, and the default ones will then call a message print function.

Parameters:

level	The level of the message.
format	A printf style format string.
...	The list of parameters for the format string.

MeHandler MeSetDebugHandler ( MeHandler n )

Set the default debug message handler function, returning the previous value.

Parameters:

n	handler function.

Returns:

the previous handler function.

MeShow MeSetDebugShow ( MeShow n )

Set the default debug message handler print function, returning the previous value.

Parameters:

n	a print function of type MeShow.

MeHandler MeSetFatalErrorHandler ( MeHandler n )

Set the default fatal error message handler function, returning the previous value.

Parameters:

n	handler function.

Returns:

the previous handler function.

MeShow MeSetFatalErrorShow ( MeShow n )

Set the default fatal error message handler print function, returning the previous value.

Parameters:

n	a print function of type MeShow.

MeHandler MeSetInfoHandler ( MeHandler n )

Set the default informational message handler function, returning the previous value.

Parameters:

n	handler function.

Returns:

the previous handler function.

MeShow MeSetInfoShow ( MeShow n )

Set the default informational message handler print function, returning the previous value.

Parameters:

n	a print function of type MeShow.

Set the default warning message handler function, returning the previous value.

Parameters:

n	handler function.

Returns:

the previous handler function.

MeShow MeSetWarningShow ( MeShow n )

Set the default warning message handler print function, returning the previous value.

Parameters:

n	a print function of type MeShow.

void MeShowStderr ( int level, const char * const string )

Print a string to stderr if the level is right.

This is the default messaging output function.

void MeShowStdout ( int level, const char * const string )

Print a string to stdout if the level is right.

This could be a default messaging output function.

void MeWarning ( int level, const char * const format, ... )

The warning message function.

Calls a message handler, and the default ones will then call a message print function.
