This class defines classification and conversion functions for the char type. It gets used by char streams for many I/O operations. The char specialization provides a number of optimizations as well.

Destructor. This function deletes table() if del was true in the constructor. |
|
Returns a pointer to the C locale mask table.
|
|
Constructor performs static initialization. This constructor is used to construct the initial C locale facet.
|
|
Constructor performs initialization. This is the constructor provided by the standard.

Narrow char array to char array. This virtual function converts each char in the range [lo,hi) to char using the simplest reasonable transformation and writes the results to the destination array. For any char in the input that cannot be converted, dfault is used instead. For an underived ctype<char> facet, the argument will be copied unchanged. do_narrow() is a hook for a derived facet to change the behavior of narrowing. do_narrow() must always return the same result for the same input. Note: this is not what you want for codepage conversions. See codecvt for that.

Convert array to lowercase. This virtual function converts each char in the range [lo,hi) to lowercase if possible. Other chars remain untouched. do_tolower() is a hook for a derived facet to change the behavior of lowercasing. do_tolower() must always return the same result for the same input.

Convert to lowercase. This virtual function converts the char argument to lowercase if possible. If not possible (for example, '2'), returns the argument. do_tolower() is a hook for a derived facet to change the behavior of lowercasing. do_tolower() must always return the same result for the same input.

Return a mask array. This function finds the mask for each char in the range [lo, hi) and successively writes it to vec. vec must have as many elements as the char array.
|
|
Test char classification. This function compares the mask table[c] to m.

Narrow char array. This function converts each char in the input to char using the simplest reasonable transformation and writes the results to the destination array. For any char in the input that cannot be converted, dfault is used instead. For an underived ctype<char> facet, the argument will be copied unchanged. This function works as if it returns ctype<char>::do_narrow(lo, hi, dfault, to). do_narrow() must always return the same result for the same input. Note: this is not what you want for codepage conversions. See codecvt for that.
