|
Structured data which is transferred using a memory read or write (for
|
||
|
example, a <code>struct stat</code>) is expected to be in a protocol-specific format
|
||
|
with all scalar multibyte datatypes being big endian. Translation to
|
||
|
this representation needs to be done both by the target before the <code>F</code>
|
||
|
packet is sent, and by <span class="sc">gdb</span> before
|
||
|
it transfers memory to the target. Transferred pointers to structured
|
||
|
data should point to the already-coerced data at any time.
