|
// - len_off:
|

// - the n-th (base 1) parameter representing the length of the string

// - or 1 if is char

|
// - or 0 if detect on run time
|

|
|
// Examples:
|
|
// int WINAPI lstrlenA(LPCSTR lpString)
|
|
// - data: 4 * 1 = 4, as lpString is the first
|
|
// - len_off: 0, as no parameter representing string length
|
|
// - type: BIG_ENDIAN, since len_off == 1
|
|
// BOOL GetTextExtentPoint32(HDC hdc, LPCTSTR lpString, int c, LPSIZE lpSize);
|
|
// - data: 4 * 2 = 0x8, as lpString is the second
|
|
// - len_off: 3, as nCount is the 3rd parameter
|
|
// - type: USING_STRING, since len_off != 1
