Detailed Description

Read HTK parameter file.

Author:

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.

Function Documentation

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.

Definition at line 60 of file rdparam.c.

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.
