50 | * The currently most frequent use of the RTAsn1 module is to decode ASN.1 byte
|

51 | * streams. In that scenario we do not allocate memory for the raw content
|

52 | * bytes, but share it with the byte stream. Also, a great number of RTASN1CORE
|

53 | * structures will never need to have any content bytes allocated with this.
|
---|
54 | *
|
---|
55 | * So, in order to avoid adding an extra 16 (64-bit) or 8 (32-bit) bytes to each
|
---|
56 | * RTASN1CORE structure just to keep track of the occational content allocation,
|
---|
57 | * we put the allocator tracking structure inside the allocation. During
|
---|
58 | * allocator operations it lives temporarily on the stack.
