| Summary | #include <ctype.h> int isgraph ( int c); /* character to test */ |
| Description | The isgraph function tests c to determine if it is a printable character (0x21-0x7E) not including space (' '). |
| Return Value | The isgraph function returns a value of 1 if c is a printable character or a value of 0 if it is not. |
| See Also | isalnum, isalpha, iscntrl, isdigit, islower, isprint, ispunct, isspace, isupper, isxdigit |
| Example |
#include <ctype.h>
#include <stdio.h> /* for printf */
void tst_isgraph (void) {
unsigned char i;
char *p;
for (i = 0; i < 128; i++) {
p = (isgraph (i) ? "YES" : "NO");
printf ("isgraph (%c) %s\n", i, p);
}
