curl_getenv(3) libcurl Manual curl_getenv(3)
NAME curl_getenv - return value for environment name
SYNOPSIS #include <curl/curl.h>
char *curl_getenv(const char *name);
DESCRIPTION curl_getenv() is a portable wrapper for the getenv() function, meant to emulate its behaviour and provide an identical interface for all oper- ating systems libcurl builds on (including win32).
AVAILABILITY 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().
RETURN VALUE 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.
NOTE Under unix operating systems, there isnt any point in returning an allocated memory, although other systems won t work properly if this isnt done. The unix implementation thus have to suffer slightly from the drawbacks of other systems.
