|
|
* For data types, All the functions below can be zero or NULL excext
|

* type and is isData, which should be your oid tag and PR_FALSE respectively
|
|
*
|
|
* For wrapping types, everything must be provided, or you will get encoder

* failures.

|
|
* If NSS doesn't already define the OID that you need, you can register
|
|
* your own with SECOID_AddEntry.

|
|
* Once you have defined your new content type, you can pass your new content
|
|
* type to NSS_CMSContentInfo_SetContent().
|

|
|
* If you are using a wrapping type you can pass your own data structure in
|
|
* the ptr field, but it must contain and embedded NSSCMSGenericWrappingData
|

* structure as the first element. The size you pass to
|
|
* NSS_CMSType_RegisterContentType is the total size of your self defined
