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.
