curl_getenv - return value for environment name
#include <curl/curl.h>
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 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 pointer.
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.
