curlgetenv(3) libcurl Manual curlgetenv(3)

NAME
       curlgetenv - return value for environment name

SYNOPSIS
       ##iinncclluuddee <>

       cchhaarr **ccuurrllggeetteennvv((ccoonnsstt cchhaarr **name));;

DESCRIPTION
       curlgetenv() is a portable wrapper for the getenv() function, meant to
       emulate its behaviour and provide an identical interface for all  oper-
       ating 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 curlxgetenv().

RREETTUURRNN VVAALLUUEE
       If  successful,  curlgetenv()  returns  a  pointer to the value of the
       specified environment. The memory it refers to is  malloc()ed  why  the
       application  must  free() this when the data has completed to serve its
       purpose. When curlgetenv(3) fails  to  find  the  specified  name,  it
       returns a null pointer.

NNOOTTEE
       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 have to suffer slightly from
       the drawbacks of other systems.
