関数

short param_qualstr2code ( char * s )

Convert a qualifier string to a binary type code.

引数:

s	[in] a string that contains qualifier strings like "_E_D_Z"

戻り値:: the converted internal binary type code, F_ERR_INVALID if failed.

short param_str2code ( char * s )

Convert a type string that contains basename and qualifiers to a binary type code.

引数:

s	[in] a string that contains base and qualifier string like "MFCC_E_D_Z"

戻り値:: the converted internal binary type code, F_ERR_INVALID if failed.

char* param_qualcode2str	(	char *	buf,
		short	type,
		boolean	descflag
	)

Convert the qualifier part of a binary type code to string.

引数:

buf	[out] buffer to store the resulting string (must have enough length)
type	[in] binary type code to convert.
descflag	[in] set to TRUE if you want result in description string instead of qualifier string.

戻り値:: buf on success, NULL on failure.

char* param_code2str	(	char *	buf,
		short	type,
		boolean	descflag
	)

Convert a binary type code to string.

引数:

buf	[out] buffer to store the resulting string (must have enough length)
type	[in] binary type code to convert.
descflag	[in] set to TRUE if you want result in description string instead of base and qualifier string.

戻り値:: buf on success, NULL on failure.
