Function Documentation

static HTK_HMM_Trans* trans_new

(

HTK_HMM_INFO *

hmm

)

[static]

Allocate a new data area and return it.

Returns:

pointer to newly allocated data.

void trans_add	(	HTK_HMM_INFO *	hmm,
		HTK_HMM_Trans *	new
	)

Add a new data to the global structure.

Parameters:

	hmm	[i/o] HMM definition data to store it
	new	[in] new data to be added

static HTK_HMM_Trans* trans_lookup	(	HTK_HMM_INFO *	hmm,
		char *	keyname
	)			[static]

Look up a data macro by the name.

Parameters:

	hmm	[in] HMM definition data
	keyname	[in] macro name to find

Returns:

pointer to the found data, or NULL if not found.

static HTK_HMM_Trans* trans_read	(	FILE *	fp,
		HTK_HMM_INFO *	hmm
	)			[static]

Read one new data and returns the pointer.

If a sub-component of this data is directly defined at here, they will be read from here and assigned to this data. If a sub-component is not defined here but a macro name referencing to the component previously defined in other place, the data will be searched by the macro name and the pointer to the found component will be assigned to this model.

Parameters:

	fp	[in] file pointer
	hmm	[i/o] HMM definition data

Returns:

pointer to the newly read data.

HTK_HMM_Trans* get_trans_data	(	FILE *	fp,
		HTK_HMM_INFO *	hmm
	)

Return a pointer to the data located at the current point.

If the current point is a macro reference, the pointer to the already defined data will be searched and returned. Otherwise, the definition of the data will be read from the current point and pointer to the newly allocated data will be returned.

Parameters:

	fp	[in] file pointer
	hmm	[i/o] HMM definition data

Returns:

pointer to the data located at the current point.

void def_trans_macro	(	char *	name,
		FILE *	fp,
		HTK_HMM_INFO *	hmm
	)

Read a new data and store it as a macro.

Parameters:

	name	[in] macro name
	fp	[in] file pointer
	hmm	[i/o] HMM definition data
