+.TH curl_getenv 3 "30 April 2004" "libcurl 7.12" "libcurl Manual"
+.SH NAME
+curl_getenv - return value for environment name
+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "char *curl_getenv(const char *" name ");"
+.ad
+.SH 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).
+.SH 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().
+.SH 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 \fIcurl_getenv(3)\fP fails
+to find the specified name, it returns a null pointer.
+.SH 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.
