Hey guys, I dont know if this is the section to put this in, but this was the closest one anyway, Im trying to modify this program so it can 'fold long lines at some reasonable length'

Any suggestions??

/* vis: make funny characters visible (version 1) */

#include <stdio.h>
#include <ctype.h>

main()
{
int c;
int i=1;

while ((c = getchar()) != EOF)
if (isascii(c) &&
(isprint(c) || c=='\n' || c=='\t' || c==' '))
i++;
putchar(c);
if(i > 65) {putchar('\n') ;i = 0;}
else
printf("\\%03o", c);
exit(0);

}
 
PUTS(3) 						     Linux Programmer's Manual							   PUTS(3)

NAME
fputc, fputs, putc, putchar, puts - output of characters and strings SYNOPSIS
#include <stdio.h> int fputc(int c, FILE *stream); int fputs(const char *s, FILE *stream); int putc(int c, FILE *stream); int putchar(int c); int puts(const char *s); DESCRIPTION
fputc() writes the character c, cast to an unsigned char, to stream. fputs() writes the string s to stream, without its trailing ''. putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once. putchar(c); is equivalent to putc(c,stdout). puts() writes the string s and a trailing newline to stdout. Calls to the functions described here can be mixed with each other and with calls to other output functions from the stdio library for the same output stream. For non-locking counterparts, see unlocked_stdio(3). RETURN VALUE
fputc(), putc() and putchar() return the character written as an unsigned char cast to an int or EOF on error. puts() and fputs() return a non-negative number on success, or EOF on error. CONFORMING TO
ANSI - C, POSIX.1 BUGS
It is not advisable to mix calls to output functions from the stdio library with low - level calls to write() for the file descriptor asso- ciated with the same output stream; the results will be undefined and very probably not what you want. SEE ALSO
