| SYNOPSIS | 
#include <dmarc.h>
OPENDMARC_STATUS_T opendmarc_policy_library_init(
	OPENDMARC_LIB_T *lib
);
One time initialization of the library for use at program startup. | 
|---|
| DESCRIPTION | 
| Called When | opendmarc_policy_library_init()
    is called after the program starts and before multi-threading operation begins. |  | 
|---|
| ARGUMENTS | 
    | Argument | Description | 
|---|
 | lib | The address of a structure of type 
        OPENDMARC_LIB_T that your code has filled out with appropriate values. |  | 
|---|
| RETURN VALUES | 
DMARC_PARSE_OKAY -- Success.
DMARC_PARSE_ERROR_NULL_CTX -- If you passed in a lib value that was NULL.
DMARC_TLD_ERROR_UNKNOWN -- If the tld_type specified is not one that the library knows about.
Other possible return values various errno values set by failure to read the TLD file.
 | 
| NOTES | 
This function is not thread safe and must only be called once and only once when the
program starts and before multi-threading begins.
If you fail to use a TLD file, the library will not be able to perform a second lookup
for a DMARC record by converting a subdomain into an organizational domain. So will only perform the
first lookup of the subdomain, possibly missing a valid DMARC record.
