Start parsing ASN.1 object.
cursor | ASN.1 object cursor |
type | Expected type, or ASN1_ANY |
extra | Additional length not present within partial cursor |
len | Length of object body, or negative error |
The object cursor will be updated to point to the start of the object body (i.e. the first byte following the length byte(s)), and the length of the object body (i.e. the number of bytes until the following object tag, if any) is returned.
If the expected type is not found, the object cursor will not be modified. If any other error occurs, the object cursor will be invalidated.
