                     31: .SH DESCRIPTION
                     32: curl_getenv() is a portable wrapper for the getenv() function, meant to
                     33: emulate its behaviour and provide an identical interface for all operating
                     34: systems libcurl builds on (including win32).
                     35: 
                     36: You must \fIcurl_free(3)\fP the returned string when you're done with it.
                     37: .SH AVAILABILITY
                     38: This function will be removed from the public libcurl API in a near future. It
                     39: will instead be made "available" by source code access only, and then as
                     40: curlx_getenv().
                     41: .SH RETURN VALUE
                     42: A pointer to a zero terminated string or NULL if it failed to find the
                     43: specified name.
                     44: .SH NOTE
                     45: Under unix operating systems, there isn't any point in returning an allocated
                     46: memory, although other systems won't work properly if this isn't done. The
                     47: unix implementation thus has to suffer slightly from the drawbacks of other
                     48: systems.
