KSTRTOUINT(9) Basic C Library Functions KSTRTOUINT(9)NAMEkstrtouint - convert a string to an unsigned int
SYNOPSIS
int kstrtouint(const char * s, unsigned int base, unsigned int * 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, but not 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.
