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 behavior and provide an identical interface for all operat‐
16       ing 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 fu‐
22       ture. 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 null-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 al‐
31       located  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.
