<H2>DESCRIPTION</H2><PRE>
|
|
curl_getenv() is a portable wrapper for the getenv() func-
|
|
tion, meant to emulate its behaviour and provide an iden-
|
|
tical interface for all operating systems libcurl builds
|
|
on (including win32).
|
|
|

|
|
<H2>RETURN VALUE</H2><PRE>
|
|
If successful, curl_getenv() returns a pointer to the
|
|
value of the specified environment. The memory it refers
|
|
to is malloc()ed why the application must free() this when
|
|
the data has completed to serve its purpose. When
|
|
<I>curl</I><B>_</B><I>getenv()</I> fails to find the specified name, it returns
|
|
a null pointer.

|
|
<H2>NOTE</H2><PRE>
|
|
Under unix operating systems, there isn't any point in
|
|
returning an allocated memory, although other systems
|
|
won't work properly if this isn't done. The unix implemen-
|
|
tation thus have to suffer slightly from the drawbacks of
|
|
other systems.
