The subject sequence is defined as the longest initial subsequence of the input string,starting with the first non-white-space character, that is of the expected form. Thesubject sequence contains no characters if the input string is empty or consists entirelyof white space, or if the first non-white-space character is other than a sign or apermissible letter or digit.If the subject sequence has the expected form and the value of base is zero, thesequence of characters starting with the first digit is interpreted as an integer constant.If the subject sequence has the expected form and the value of base is between 2 and36, it is used as the base for conversion.If the subject sequence begins with a minus sign, the value resulting from theconversion is negated.A pointer to the final string is stored in the object pointed to by endptr, provided thatendptr is not a null pointer.If the subject sequence is empty or does not have the expected form, no conversion isperformed, the value of nptr is stored in the object pointed to by endptr, provided thatendptr is not a null pointer.strtoull returns the converted value, if any. If no conversion could be performed, zerois returned. If the correct value is outside the range of representable values,LLONG_MAX (page 250) or ULLONG_MAX (page 252) is returned according to thesign of the value, if any, and the value of the macro ERANGE is stored in errno (page247).Portabilitystrtoull conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).ultoaSynopsisDescription#include char *ulltoa(unsigned long long val, char *buf, int radix);ulltoa converts val to a string in base radix and places the result in buf.ulltoa returns buf as the result.If radix is greater than 36, the result is undefined.Portability ulltoa is an extension to the standard C library provided by CrossWorks C.See Also itoa (page 299) ltoa (page 301) lltoa (page 300) ultoa (page 309) utoa (page 310)ultoaSynopsis#include char *ultoa(unsigned long val, char *buf, int radix);Chapter 28 - General utilities309
