Converts a binary number into a string representation of a hexadecimal number.

void HexFromBin(
  LPBYTE pb,
  int cb,
  LPSTR sz


[in] Pointer to the binary data to be converted.


[in] Size, in bytes, of the binary data pointed to by the pb parameter.


[out] Pointer to a null-terminated ASCII string representing the binary data in hexadecimal digits.

The HexFromBin function takes a pointer to a unit of binary data whose size is indicated by the cb parameter. It returns in the sz string, within (2*cb)+1 bytes of memory, a representation of this binary information in hexadecimal numbers. If the byte value is decimal 10, for example, the hexadecimal string will be 0A, so one byte converts to two bytes in the string.
