// ************************************************************
|

|
|
// The following macros use these type specifiers in any passed format strings
|
||
|
|
// note that I tried to keep them similar to printf in most cases, but not always
|
||
|
|
// in general, the type specifiers are case-sensitive. Also, a caps type specifier
|
||
|
|
// usually means that the output will be in caps, as opposed to lowercase (i.e. BOOLs
|
||
|
|
// and HEX numbers)
|
||
|
|
// *** Basic types
|
||
|
|
// int, LONG -> %d, %D
|
||
|
|
// UINT, ULONG, DWORD ->%ud, %uD, %x, %X
|
||
|
|
// BOOL -> %b, %B
|
||
|
|
// pointer -> %p, %P (hex)
|
||
|
|
// string -> %s
|
||
|
|
// wide string -> %ws
|
||
|
|
// HANDLE -> %h
|
||
|
|
// LARGE_INTEGER, ULARGE_INTEGER -> %ld, %uld
