Functions

SPHINXBASE_EXPORT void ucase (char *str)
 Convert str to all upper case.
SPHINXBASE_EXPORT void lcase (char *str)
 Convert str to all lower case.
SPHINXBASE_EXPORT int32 strcmp_nocase (const char *str1, const char *str2)
 (FIXME! The implementation is incorrect!) Case insensitive string compare.
SPHINXBASE_EXPORT int32 strncmp_nocase (const char *str1, const char *str2, size_t len)
 Like strcmp_nocase() but with a maximum length.


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,

Return the usual -1, 0, +1, depending on str1 <, =, > str2 (case insensitive, of course).

Parameters:
str1 is the first string.
