22 .TH curl_getenv 3 "30 April 2004" "libcurl 7.12" "libcurl Manual"
23 .SH NAME
24 curl_getenv - return value for environment name
25 .SH SYNOPSIS
26 .B #include <curl/curl.h>
27 .sp
28 .BI "char *curl_getenv(const char *" name ");"
29 .ad
30 .SH DESCRIPTION
31 curl_getenv() is a portable wrapper for the getenv() function, meant to
32 emulate its behaviour and provide an identical interface for all operating
33 systems libcurl builds on (including win32).
34 .SH AVAILABILITY
35 This function will be removed from the public libcurl API in a near future. It
36 will instead be made "available" by source code access only, and then as
37 curlx_getenv().
38 .SH RETURN VALUE
39 If successful, curl_getenv() returns a pointer to the value of the specified
40 environment. The memory it refers to is malloc()ed so the application must
41 free() this when the data is no longer needed. When \fIcurl_getenv(3)\fP fails
42 to find the specified name, it returns a null pointer.
43 .SH NOTE
44 Under unix operating systems, there isn't any point in returning an allocated
45 memory, although other systems won't work properly if this isn't done. The
46 unix implementation thus has to suffer slightly from the drawbacks of other
47 systems.
