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 behavior and provide an identical interface for all
       operating systems libcurl builds on (including win32).

       You must _free&section=3">curl_free(3) the returned string when you're done with it.

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
       A pointer to a null-terminated string or NULL if it failed to find the
       specified name.

NOTE
       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 has to suffer slightly from
       the drawbacks of other systems.
