Defined in header <locale>

template< class charT >
charT tolower( charT ch, const locale& loc );

Converts the character ch to lowercase if possible, using the conversion rules specified by the given locale's std::ctype facet.


[edit] Parameters

ch - character
loc - locale

[edit] Return value

Returns the lowercase form of ch if one is listed in the locale, otherwise return ch unchanged.

[edit] Notes

Only 1:1 character mapping can be performed by this function, e.g. the Greek uppercase letter 'Σ' has two lowercase forms, depending on the position in a word: 'σ' and 'ς'. A call to std::tolower cannot be used to obtain the correct lowercase form in this case.
