Name

isspace function — Tests for a white space character

Synopsis

int isspace(int c)

The isspace function returns true (nonzero) if c is a whitespace character. In the "C" locale, the space (' '), form feed ('\f'), newline ('\n'), carriage return ('\r'), horizontal tab ('\t'), and vertical tab ('\v') characters are whitespace, but backspace ('\b') is not. Different locales can define other whitespace characters.
