KSTRTOLL(9)                         Basic C Library Functions                         KSTRTOLL(9)



NAME
       kstrtoll - convert a string to a long long

SYNOPSIS
       int kstrtoll(const char * s, unsigned int base, long long * res);

ARGUMENTS
       s
           The start of the string. The string must be null-terminated, and may also include a
           single newline before its terminating null. The first character may also be a plus
           sign or a minus sign.

       base
           The number base to use. The maximum supported base is 16. If base is given as 0, then
           the base of the string is automatically detected with the conventional semantics - If
           it begins with 0x the number will be parsed as a hexadecimal (case insensitive), if it
           otherwise begins with 0, it will be parsed as an octal number. Otherwise it will be
           parsed as a decimal.

       res
           Where to write the result of the conversion on success.

DESCRIPTION
       Returns 0 on success, -ERANGE on overflow and -EINVAL on parsing error. Used as a
       replacement for the obsolete simple_strtoull. Return code must be checked.
