Function Documentation

static void update_gconst

(

HTK_HMM_Dens *

d

)

[static]

Calculate and set the GCONST value.

Parameters:

d

[i/o] density data

Definition at line 38 of file rdhmmdef_dens.c.

Referenced by dens_read().

static HTK_HMM_Dens* dens_new

(

HTK_HMM_INFO *

hmm

)

[static]

Allocate a new data area and return it.

Returns:

pointer to newly allocated data.

void dens_add	(	HTK_HMM_INFO *	hmm,
		HTK_HMM_Dens *	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

Definition at line 79 of file rdhmmdef_dens.c.

Referenced by def_dens_macro(), get_dens_data(), and rd_dens().

HTK_HMM_Dens* dens_lookup	(	HTK_HMM_INFO *	hmm,
		char *	keyname
	)

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_Dens* dens_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	[in] HMM definition data

Returns:

pointer to the newly read data.

Definition at line 139 of file rdhmmdef_dens.c.

Referenced by def_dens_macro(), and get_dens_data().

HTK_HMM_Dens* get_dens_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_dens_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
