Function Documentation

QI_API int qi::argc

(

)

Get argc.

Returns:

return argc if qi::init is call, -1 otherwise

Examples:

boost_filesystem_example.cpp, log_example.cpp, qiconvloc_example.cpp, and qipath_example.cpp.

const char ** qi::argv

(

)

Get argv.

Returns:

return argv if qi::init is call, NULL otherwise

Examples:

boost_filesystem_example.cpp, log_example.cpp, qiconvloc_example.cpp, and qipath_example.cpp.

const char * qi::program

(

)

Return the current program.Computed using specific OS API:

• Apple : _NSGetExecutablePath
• Linux : reading "/proc/self/exe"
• Windows: GetModuleFileName

If the former API fail it will try to guess the value from argv[0]. For this method to work qi::init(argc, argv) should have been called in the main.

Returns:

full path to the current running program

const codecvt_type & qi::unicodeFacet

(

)

utf8 facet

return a facet object that can be used by stl (iostream, locale, ..) and std::locale compliant library like boost::filesystem.

this class allow convertion between utf8(char) and utf16/32(wchar).

Returns:

utf8 implementation for std::codecvt<wchar_t, char, std::mbstate_t>
