c atoi() for wide chars on linux?
Is there a c atoi() equivalent for wide chars on Linu开发者_C百科x? I can find something for MS (wtoi) but I can find anything in a standard Linux lib.
You can use wcstol to convert from wide strings to integer values.
It is unusual for a Linux program to use wchar_t
type.
The reason being that Linux uses utf-8 as the standard encoding. char const*
strings are assumed to be utf-8 strings by glibc. Ascii digits and utf-8 digits have the same byte representation, so that atoi() works both on ascii and utf-8 strings.
Having said that, look in #include <wchar.t>
, it provides wcstol()
.
