For hexadecimal numbers, the numerals for the numbers 10 to 15 are represented by the letters A-F, as usual.

The function converts a hexadecimal string into binary data and returns the number of successfully converted data bytes as result. Only spaces may be used as separators in the hexadecimal string to be converted. Lower and upper case …
