std::ctype<char>::ctype (3) - Linux Man Pages
Defined in header <locale>
explicit ctype( const mask* tbl = 0, bool del = false, std::size_t refs = 0);
Creates a std::ctype<char> facet and forwards the starting reference count refs to the base class constructor, locale::facet::facet().
If tbl is null, classic_table() is used by all classification member functions. Otherwise, tbl must be a pointer to the first element of an array of masks, at least std::ctype<char>::table_size in size, and that array is used by all of this facet's classification member functions.
If del is true, it is assumed that the array was allocated with new, and the destructor of this facet will call delete tbl
tbl - classification table to use or a null pointer
del - indicator whether the table needs to be deleted.
refs - starting reference count
