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 curl_free(3) the returned string when you are done with it.

EXAMPLE

         char *width = curl_getenv("COLUMNS");
         if(width) {
           /* it was set! */
           curl_free(width);
         }

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 is no point in returning an allocated memory, although
       other systems will not work properly if this is not done. The unix implementation thus has
       to suffer slightly from the drawbacks of other systems.
