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() func- tion, meant to emulate its behaviour and provide an iden- tical interface for all operating systems libcurl builds on (including win32).
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.
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 implemen- tation thus have to suffer slightly from the drawbacks of other systems.
Surely there are some, you tell me!
