32 curl_getenv() is a portable wrapper for the getenv() function, meant to
33 emulate its behaviour and provide an identical interface for all operating
34 systems libcurl builds on (including win32).
36 This function will be removed from the public libcurl API in a near future. It
37 will instead be made "available" by source code access only, and then as
40 If successful, curl_getenv() returns a pointer to the value of the specified
41 environment. The memory it refers to is malloc()ed so the application must
42 free() this when the data is no longer needed. When \fIcurl_getenv(3)\fP fails
43 to find the specified name, it returns a null pointer.
45 Under unix operating systems, there isn't any point in returning an allocated
46 memory, although other systems won't work properly if this isn't done. The
47 unix implementation thus has to suffer slightly from the drawbacks of other
