Use the -l c option to qcc to link against this library. This library is usually included automatically.

The towctrans() function converts wc, using the mapping described by category. The following functions are equivalent:

Function	Equivalent wctrans() call
`towlower( wc )`	`towctrans( wc, wctrans("tolower") )`
`towupper( wc )`	`towctrans( wc, wctrans("toupper") )`

The corresponding converted wide character when the argument is valid; otherwise, the original wide character.
