getenv(3C)                     DG/UX R4.11MU05                    getenv(3C)


NAME
       getenv - return value for environment name

SYNOPSIS
       #include <stdlib.h>

       char *getenv (const char *name);

DESCRIPTION
       getenv searches the environment list [see environ(5)] for a string of
       the form name=value and, if the string is present, returns a pointer
       to the value in the current environment.  Otherwise, it returns a
       null pointer.

       The environment information is global to all threads in a process.
       Any thread in a process may issue a getenv call.

       See putenv(3C) for information on changing the environment
       information in a multi-threaded application.
