Returns the value of the environment variable with name \a
varName. To get the variable string, use QByteArray::constData().
To convert the data to a QString use QString::fromLocal8Bit().
\note qgetenv() was introduced because getenv() from the standard
C library was deprecated in VC2005 (and later versions). qgetenv()
uses the new replacement function in VC, and calls the standard C
library's implementation on all other platforms.
\warning Don't use qgetenv on Windows if the content may contain
non-US-ASCII characters, like file paths.
