Detailed Description

Read HTK parameter file.

The byte order of HTK parameter file is assumed as big endian. If not, however, these functions try to read with forcing byte (re-)swapping.

When "_C" (compressed) or "_K" (CRC checksum added) exists in the file, they are processed in these functions. Then, after reading finished, these qualifiers are removed from its parameter type code.

static boolean myread	(	char *	buf,
		size_t	unitbyte,
		int	unitnum,
		FILE *	fp
	)			[static]

Read binary data from a file pointer, with byte swapping.

Parameters:

	buf	[out] buffer to store read data
	unitbyte	[in] size of a unit in bytes
	unitnum	[in] number of unit to read
	fp	[in] file pointer

Returns:

TRUE if specified number of unit was successfully read, FALSE if failed.

static boolean read_param	(	FILE *	fp,
		HTK_Param *	pinfo
	)			[static]

Read in a HTK parameter file from fp .

Parameters:

	fp	[in] file pointer
	pinfo	[in] parameter data to store the read informations

Returns:

TRUE on success, FALSE on failure.
