kstrtouint - convert a string to an unsigned int
2. SYNOPSIS ▲
int kstrtouint(const char * s , unsigned int base , unsigned int * res );
3. ARGUMENTS ▲
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.
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.
Where to write the result of the conversion on success.
4. 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.
