Checks if the given character is whitespace character as classified by the currently installed C locale. In the default locale, the whitespace characters are the following:
- space (
0x20, ' ') - form feed (
0x0c, '\f') - line feed (
0x0a, '\n') - carriage return (
0x0d, '\r') - horizontal tab (
0x09, '\t') - vertical tab (
0x0b, '\v')
The behavior is undefined if the value of ch is not representable as unsigned char and is not equal to EOF.
