Written by Chamara Withanachchi   

Retrieves a C string containing the value of the environment variable whose name is specified as argument. If the requested variable is not part of the environment list, the function returns a NULL pointer.

The string pointed by the pointer returned by this function shall not be modified by the program.

The same memory location may be used in subsequent calls to getenv, overwriting the previous content.



     D getenv          PR              *   extProc('getenv')
     D  envVar                         *   Value Options(*STRING)
     D userAddr         S            15A
          userAddr = %str(getenv('REMOTE_ADDR'));
