Detailed Description

Locale-independent implementation of case swapping operation.

This function implements ASCII-only case switching and comparison related operations, which do not depend on the locale and are guaranteed to exist on all versions of Windows.

Function Documentation

SPHINXBASE_EXPORT void lcase

(

char *

str

)

Convert str to all lower case

Parameters:

str

is a string.

SPHINXBASE_EXPORT int32 strcmp_nocase	(	const char *	str1,
		const char *	str2
	)

(FIXME! The implementation is incorrect!) Case insensitive string compare. Return the usual -1, 0, +1, depending on str1 <, =, > str2 (case insensitive, of course).

Parameters:

	str1	is the first string.
	str2	is the second string.

SPHINXBASE_EXPORT int32 strncmp_nocase	(	const char *	str1,
		const char *	str2,
		size_t	len
	)

Like strcmp_nocase() but with a maximum length.

SPHINXBASE_EXPORT void ucase

(

char *

str

)

Convert str to all upper case.

Parameters:

str

is a string.
