short isspace (short c); |
Checks whether a character is a white space.
isspace returns nonzero if c is a space, tab, carriage return, new line, vertical tab, or formfeed (0x09 to 0x0D and 0x20), otherwise it returns zero. It is a relatively small inline function which is implemented using GNU C smart macros.
