curl_getenv - return value for environment name
char *curl_getenv(const char *name);
curl_getenv() is a portable wrapper for the getenv() function, meant to emulate its behav-
iour and provide an identical interface for all operating systems libcurl builds on
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().
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
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.
