NAME
       curl_getenv - return value for environment name

SYNOPSIS
       #include <curl/curl.h>

       char *curl_getenv(const char *name);

DESCRIPTION
       curl_getenv()  is  a  portable wrapper for the getenv() function, meant to emulate its behaviour and provide an identical interface for all
       operating systems libcurl builds on (including win32).

RETURN VALUE
       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 curl_getenv() fails to find the specified name, it
       returns a null pointer.

NOTE
       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 implementation thus have to suffer slightly from the drawbacks of other systems.

SEE ALSO
       getenv(3C),

BUGS
       Surely there are some, you tell me!
