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 behaviour and provide an identical interface for all operating
systems libcurl builds on (including win32).
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
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.
Under unix operating systems, there isnt any point in returning an allocated
memory, although other systems wont work properly if this isnt done. The
unix implementation thus has to suffer slightly from the drawbacks of other
