Typedefs
typedef int(*)	EdtMsgFunction (void *target, int level, const char *message)
	An EdtMsgFunction is a function which outputs a message if that message's level is high enough.
typedef _edt_msg_handler	EdtMsgHandler
	Structure used by the Message Handler Library to control the output of messages.
Enumerations
enum	EdtReturn
Functions
int	edt_get_verbosity (void)
int	edt_msg (int level, const char *format,...)
	Submits a message to the default message handler, which will conditionally (based on the flag bits) send the message to the default message handler function.
void	edt_msg_add_level (EdtMsgHandler *msg_p, int level)
	Sets the message level to the combination of the specified level with the message handler's previous level.
void	edt_msg_close (EdtMsgHandler *msg_p)
	Closes and frees up memory associated with a message handler.
EdtMsgHandler *	edt_msg_default_handle (void)
	Gets the default message handler.
int	edt_msg_default_level (void)
	Gets the message level that messages must match in order to be handled by the default message handler.
int	edt_msg_get_level (EdtMsgHandler *msg_p)
	Gets the message level that messages must match in order to be handled by the message handler msg_p.
void	edt_msg_init (EdtMsgHandler *msg_p)
	Initializes a message handler with default values.
void	edt_msg_init_files (EdtMsgHandler *msg_p, FILE *file, int level)
	Initializes a message handler to use the specified file and level.
void	edt_msg_init_names (EdtMsgHandler *msg_p, char *file, int level)
	Initializes a message handler to use the named file and specified level.
char *	edt_msg_last_error (void)
	Gets the message last sent to the output by the edt message handling system.
int	edt_msg_output (EdtMsgHandler *msg_p, int level, const char *format,...)
	Submits a message using the msg_p message handler, which will conditionally (based on the flag bits) send the message to the handler's function.
int	edt_msg_output_perror (EdtMsgHandler *msg_p, int level, const char *message)
	Conditionally (based on the flag bits) outputs message, followed by the last system error message, to msg_p.
int	edt_msg_output_printf_perror (EdtMsgHandler *msg_p, int level, const char *format,...)
	Writes to the specified EdtMsgHandler a caller-specified message (in the printf-style format) followed by the last system error message.
int	edt_msg_perror (int level, const char *msg)
	Conditionally outputs a system perror using the default message handler.
int	edt_msg_printf_perror (int level, const char *format,...)
	Outputs a caller-specified message to the output, followed by the last system error message.
void	edt_msg_set_file (EdtMsgHandler *msg_p, FILE *f)
	Sets the output file pointer for the message handler.
void	edt_msg_set_function (EdtMsgHandler *msg_p, EdtMsgFunction f)
	Sets the function to call when a message event occurs.
void	edt_msg_set_level (EdtMsgHandler *msg_p, int newlevel)
	Sets the "message level" flag bits that determine whether to call the message handler for a given message.
void	edt_msg_set_name (EdtMsgHandler *msg_p, const char *f)
	Sets the output file to the named file.
void	edt_msg_set_target (EdtMsgHandler *msg_p, void *t)
	Sets the target in the message handler.
void	edt_set_verbosity (int verbose)
int	lvl_printf (int delta, char *format,...)
