| SYNOPSIS |
#include <dkim.h>
bool dkim_sig_hdrsigned(
DKIM_SIGINFO *sig,
char *hdr
);
Determine whether or not a particular header was covered by a specific
signature on a message.
|
|---|
| DESCRIPTION |
| Called When |
dkim_sig_hdrsigned() can be called at any time after
headers have been processed for a message being signed or
verified, essentially after a call to
dkim_eoh(). |
|
|---|
| ARGUMENTS |
| Argument | Description |
|---|
| sig |
Signature-specific handle.
|
| hdr |
The name of the header to be checked.
|
|
|---|
| RETURN VALUES |
| Value | Description |
|---|
| TRUE |
The header named by hdr was included in the
signature referenced by sig.
|
| FALSE |
sig did not cover hdr.
|
|
|---|
| NOTES |
- The check performed by this function is fairly simple: it will
see if hdr appears in the "h=" tag for the signature
identified by sig. It does not guarantee that a specific
instance of that header was signed, which is relevant for headers
that appear more than once (e.g. Received:).
