Routine Description:
This function locates an environment variable and returns its value.
Arguments:
Variable - Supplies a pointer to a zero terminated environment variable
name.
Length - Supplies the length of the value buffer in bytes.
Buffer - Supplies a pointer to a buffer that receives the variable value.
Return Value:
ESUCCESS is returned if the enviroment variable is located. Otherwise,
ENOENT is returned.
