isprint Function (Macro)

ctype.h

short isprint (short c);

Checks whether a character is a printing character.

isprint returns nonzero if c is a printing character, otherwise it returns zero. In TIOS, all characters in a range 0x0E to 0xFF and 0x0B are marked as "printable". isprint is a relatively small inline function which is implemented using GNU C smart macros.
