I am using Detours 3.0 to hook onto a function I obtained from Ida Pro. The problem is I came across a function which I cannot seem to hook which is due to either invalid arguements or the fact that it uses a variable arguement list.
int (*MakePacketBuffer)(const char * buf, int len, const char * splitstr, ...); #define MakePacketBufferProto int (*)(const char *, int, const char *, ...)
That is what I imagine the parameters to be like, in Ida Pro its actually shown like this:
int sub_66EEF0(int a1, int a2, const char *a3, ...)
How that function is called in Ida:
sub_66EEF0(buf, 2048, "%c%c%c%c%s%c%c", v15, 250, v20, v21, v22, v23, v25);
