3 Out-of-Process Method Invocation:
5 eax: pointer to parameter info block (PIB)
7 Call 0x7fff0000 to invoke the method.
10 ebx, esi, edi, ebp, esp: preserved
11 eax: pointer to exception, or NULL if none
12 If there is an exception, the user part of the syscall
13 function will search for an exception handling function
14 that covers the calling address. If none is found,
15 it will assume that it is a language without exception
16 handling, and return the exception to the caller in eax.
17 edx: length of exception segment, if any
22 edx: segment zero size
25 esp, ebp, esi, edi: NULL.
27 Jump to 0x7fff0080 to return.
30 eax: pointer to exception, or NULL if none
31 edx: length of exception segment, if any
32 ebx, ecx, esi, edi, ebp, esp: may be clobbered
35 eax, edx, ecx: syscall arguments.
37 Call 0x7fff0000 + 0x80 * syscallnum
40 edx, ecx: may be clobbered
