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

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

AVAILABILITY

       Always

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 does not work properly if this is not done.  The  unix  implementation  thus
       suffers slightly from the drawbacks of other systems.
