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 behavior and provide an identical interface for all operat-
ing systems libcurl builds on (including win32).
You must curl_free(3) the returned string when you are done with it.
EXAMPLE
char *width = curl_getenv("COLUMNS");
if(width) {
/* it was set! */
curl_free(width);
}
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
A pointer to a null-terminated string or NULL if it failed to find the
specified name.
NOTE
Under unix operating systems, there is no point in returning an allo-
cated memory, although other systems will not work properly if this is
not done. The unix implementation thus has to suffer slightly from the
drawbacks of other systems.
