Member Function Documentation

getenv()

std::string PosixEnvironment::getenv ( const std::string &  key ) const

overridevirtual

Same as std::getenv, but takes & returns UTF8-encoded keys and values on all platforms.

Note that on Windows std::getenv doesn't switch to UTF8 even if UnicodeCrt is used (aka std::setlocale(LC_ALL, ".UTF-8")).

Returns an empty string for non-existent environment variables, and thus doesn't distinguish between empty and non-existent values (and you shouldn't, either).

Parameters

key	UTF8-encoded name of the environment variable to query.

Returns

UTF8-encoded value of the environment variable.

Implements Environment.

path()

std::string PosixEnvironment::path ( EnvironmentPath  path ) const

overridevirtual

Accessor for various system paths.

Parameters

path	Path to get.

Returns

UTF8-encoded path, or an empty string in case of an error.

Implements Environment.

queryRegistry()

std::string PosixEnvironment::queryRegistry ( const std::string &  path ) const

overridevirtual

Windows-only function for querying the registry. Always returns an empty string on non-Windows systems.

Parameters

path	UTF8-encoded registry path to query.

Returns

UTF8-encoded value at the given path, or an empty string in case of an error.

Implements Environment.

setenv()

void PosixEnvironment::setenv ( const std::string &  key, const std::string &  value  ) const

overridevirtual

Same as POSIX setenv(key, value, 1). Takes UTF8-encoded keys and values on all platforms.

Parameters

key	UTF8-encoded name of the environment variable to set.
value	UTF8-encoded value of the environment variable.

Implements Environment.
