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 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.
