Function Documentation

int initialize

(

Initialization at loading time (optional).

If defined, this will be called just before this plugin is loaded to Julius. if this returns -1, the whole functions in this file will not be loaded.

This function is OPTIONAL.

Returns:

0 on success, -1 on failure.

Definition at line 63 of file generic_callback.c.

int get_plugin_info	(	int	opcode,
		char *	buf,
		int	buflen
	)

Get information of this plugin (required).

This function should return informations of this plugin file. The required info will be specified by opcode:

• 0: return description string of this file into buf

This will be called just after Julius find this file and after initialize().

Parameters:

	opcode	[in] requested operation code
	buf	[out] buffer to store the return string
	buflen	[in] maximum length of buf

Returns:

0 on success, -1 on failure. On failure, Julius will ignore this plugin.

static void status_recready	(	Recog *	recog,
		void *	dummy
	)			[static]

A sample callback function to output RECREADY message.

Parameters:

	recog	[in] engine instance
	dummy	[in] callback argument (dummy)

Definition at line 133 of file generic_callback.c.

int startup

(

void *

data

)

plugin function that will be called after engine startup.

When the function of this name is defined in a plugin, this will be called just after Julius finished all startup sequence and before input and recognition start.

In this example, this function registers the local function status_recready() as a CALLBACK_EVENT_SPEECH_READY callback. This callback will be called on every time Julius is ready for recognition for the next incoming input.

Parameters:

data

[in] a data pointer, actually a pointer to an engine instance.

Returns:

0 on success, -1 on error. On error, Julius will exit immediately.
