NAME

6       curl_getenv - return value for environment name
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       char *curl_getenv(const char *name);
12

DESCRIPTION

14       curl_getenv() is a portable wrapper for the getenv() function, meant to
15       emulate its behaviour and provide an identical interface for all  oper‐
16       ating systems libcurl builds on (including win32).
17
18       You must curl_free(3) the returned string when you're done with it.
19

AVAILABILITY

21       This  function  will  be  removed from the public libcurl API in a near
22       future. It will instead be made "available" by source code access only,
23       and then as curlx_getenv().
24

RETURN VALUE

26       A  pointer to a zero terminated string or NULL if it failed to find the
27       specified name.
28

NOTE

30       Under unix operating systems, there isn't any  point  in  returning  an
31       allocated  memory,  although  other systems won't work properly if this
32       isn't done. The unix implementation thus has to  suffer  slightly  from
33       the drawbacks of other systems.
