SYNOPSIS |
#include <dkim.h>
DKIM_STAT dkim_set_policy_lookup(
DKIM_LIB *libdkim,
int (*func) (DKIM *dkim,
unsigned char *buf,
size_t buflen));
);
Defines a function which should do policy lookups rather than implementing
the DKIM specification (e.g a DNS lookup).

ARGUMENTS |
Argument | Description |
libdkim |
Library-specific handle, returned by
dkim_init().
|
func |
A pointer to a function which the library should use in place
of its own code to do policy lookups. The function will receive
three things: A DKIM handle
referencing the job being processed, a pointer to a buffer that
should receive the result of the policy lookup, and the number of
bytes available there. The function should return 1 if the
policy retrieval succeeded, 0 if there were no errors but no policy
was found, and -1 on error. If NULL, the internal policy lookup
implementation will be used.

NOTES |
- This function is a local addition to the formal API specification
and is experimental only. It may not appear in other implementations.
