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.

Definition in file case.h.

Macro Definition Documentation

◆ LOWER_CASE

#define LOWER_CASE ( c )

Value:

((((c) >= 'A') && ((c) <= 'Z')) ? (c+32) : c)

Return lower case form for c.

Definition at line 97 of file case.h.

◆ UPPER_CASE

#define UPPER_CASE ( c )

Value:

((((c) >= 'a') && ((c) <= 'z')) ? (c-32) : c)

Return upper case form for c.

Definition at line 92 of file case.h.

Function Documentation

◆ lcase()

SPHINXBASE_EXPORT void lcase ( char * str )

Convert str to all lower case.

Parameters

str	is a string.

◆ strcmp_nocase()

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).
