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

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

       If  successful,  curl_getenv() returns a pointer to the value of the specified environment. The memory it
       refers to is malloc()ed so the application must free() this when the  data  is  no  longer  needed.  When
       curl_getenv(3) fails to find the specified name, it returns a null pointer.

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.
