# Implements the function:
|
|
# const PSOXBVersionInfo* @ eax [/none] get_version();
|
|
# The return opcode is not included in this fragment.
|
|
#
|
|
# The returned structure is:
|
|
# struct PSOXBVersionInfo {
|
|
# /* 00 */ uint32_t specific_version;
|
|
# /* 04 */ void* check_addr;
|
|
# /* 08 */ void (**MmSetAddressProtect)(void* addr @ [esp+4], uint32_t size @ [esp + 8], uint32_t flags @ [esp+0xC]);
|
|
# /* 0C */ uint32_t @ eax (**MmQueryAddressProtect)(void* addr @ [esp+4]);
|
|
# /* 10 */ void* @ eax (*malloc7)(uint32_t size @ ecx, AllocatorInstance* instance @ edx);
|
|
# /* 14 */ AllocatorInstance** malloc7_instance; // For use with malloc7
|
|
# };
|
|
#
|
