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).

AVAILABILITY
       This function will be removed from the public libcurl API in a near future. It will instead be made "available" by source code access only,
       and then as curlx_getenv().

RETURN VALUE
       If  successful,	curl_getenv()  returns	a  pointer to the value of the specified environment. The memory it refers to is malloc()ed so the
       application must free() this when the data is no longer needed. When curl_getenv(3) 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 has to suffer slightly from the drawbacks of other systems.
