SDL_strtoull - Parse an unsignedlonglong from a string.

       This function is available since SDL 3.2.0.

       If  str  starts  with whitespace, then those whitespace characters are skipped before attempting to parse
       the number.

       If the parsed number does not fit inside an unsignedlonglong , the  result  is  clamped  to  the  maximum
       representable unsignedlonglong value.

str    The null-terminated string to read. Must not be NULL.

       endp   If  not NULL, the address of the first invalid character (i.e. the next character after the parsed
              number) will be written to this pointer.

       base   The base of the integer to read. Supported values are 0 and 2 to 36 inclusive. If 0, the base will
              be inferred from the number's prefix (0x for hexadecimal, 0 for octal, decimal otherwise).
