.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.
