How to get value of an environment variable

28 01 2012

Windows Environment Variables hold some system paths or user defined paths. How can we read the contents of a specified environment variable.

There is an API GetEnvironmentVariable, which retrieves the contents of the specified variable from the environment block of the calling process.



void ReadEnvironmentVariable()
	GetEnvironmentVariable( _T("TMP"), tcPath, MAX_PATH );

This function can retrieve either a system environment variable or a user environment variable.
