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
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 implementation
thus have to suffer slightly from the drawbacks of other systems.
Surely there are some, you tell me!
