Some notes on the API
LP_FRONTIERSET AllocFrontierSet(); // Create the generic frontier set data structure
void FreeFrontierSet(LP_FRONTIERSET); // Destroy the in memory representation of the frontier set
void Add(LP_FRONTIERSET, unsigned char* data, int length); // Add an element to the frontier set. The element in length bytes long and contains data
int GenerateFrontierSet(LP_FRONTIERSET, char* buffer, int buffersize);
// Output the frontier to a buffer. // The buffer is buffersize bytes big and pointed to by buffer // The return value is the number of chars that would be copied to the buffer if the full // output was written // Ie the return value is how big the buffer should be // To work out how big to make the buffer. set buffer to null and buffersize to zero // // The result is a buffer full of c strings. A csting is a array of characters followed by a NULL. // The next char in the buffer is then the next string. The final string is just a NULL (ie a // double NULL the first one ends the last string the next one is the empty string. // // The output string. This is a bitwise frontier set we evaluate the bytes in order and the bits // from the most significant to the least significant. // // The string can contain te following values '0', '1' or 'T' // '0' the next bit value should be 0 // '1' the next bit value should be 1 // 'T' the byte (unsigned char) array terminates here.
// Use the string returning syntax of this guy // http://www.cplusplus.com/reference/cstdio/snprintf/ // // for reference but don't use // https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-findfirstfilenamew // and // https://cryptsoft.com/pkcs11doc/v220/pkcs11__all_8h.html#aC_Encrypt
BOOL Contains(LP_FRONTIERSET, unsigned char* data, int length)
Add example function that returns iff the given data is in the frontier set.
// LP_FRONTIERSET the set to test // data + length the element to test for // WOrks by calleding GenerateFrontierSet then iterating the entire set looking for a match.
