Updated terminology in docs, comments and phrases to refer to C strings as "null-terminated". Done to unify with how most other C oriented docs refer of them and what users in general seem to prefer (based on a single highly unscientific poll on twitter). Reported-by: coinhubs on github Fixes #5598 Closes #5608

.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 ");"
|
|

|
.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).
|
|
|
|
You must \fIcurl_free(3)\fP the returned string when you're done with it.
|
|
.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
|
|
A pointer to a null-terminated string or NULL if it failed to find the
|
|
specified name.
|
|
.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.
