I´m writing this program in QNX , I`m kinda new to UNIX and programing in general, and when I try to run it it gives me the Memory Fault error. Can anyone help?
Its supposed to print the scanned string in to a second terminal window (ttpy1), so I open the two terminals before running the program but it gives me the Memory error.
Hello To All!
Now anfd then I receive a message on my console:
Segmentation fault (core dumped)
What does it mean? Or more precisely what are the implications?

I use SCO UNIX 5.07 on a Compaq Proliant Machine. Each time I press the Escape or Delete key while running a program or issuing a FoxBase+ command from the dot prompt, I receive the error message: "Memory Fault - Core Dumped" and the screen locks up immediately.
I would appreciate if necessary... (0 Replies)

setbuffer
SETBUF(3) Linux Programmer's Manual SETBUF(3)NAME
setbuf, setbuffer, setlinebuf, setvbuf - stream buffering operations
SYNOPSIS
#include <stdio.h>
void setbuf(FILE *stream, char *buf);
void setbuffer(FILE *stream, char *buf, size_tsize);
void setlinebuf(FILE *stream);
int setvbuf(FILE *stream, char *buf, int mode , size_t size);
DESCRIPTION
The three types of buffering available are unbuffered, block buffered, and line buffered. When an output stream is unbuffered, information
appears on the destination file or terminal as soon as written; when it is block buffered many characters are saved up and written as a
block; when it is line buffered characters are saved up until a newline is output or input is read from any stream attached to a terminal
device (typically stdin). The function fflush(3) may be used to force the block out early. (See fclose(3).) Normally all files are block
buffered. When the first I/O operation occurs on a file, malloc(3) is called, and a buffer is obtained. If a stream refers to a terminal
(as stdout normally does) it is line buffered. The standard error stream stderr is always unbuffered by default.
The setvbuf function may be used on any open stream to change its buffer. The mode parameter must be one of the following three macros:
_IONBF unbuffered
_IOLBF line buffered
_IOFBF fully buffered
Except for unbuffered files, the buf argument should point to a buffer at least size bytes long; this buffer will be used instead of the
current buffer. If the argument buf is NULL, only the mode is affected; a new buffer will be allocated on the next read or write opera-
tion. The setvbuf function may only be used after opening a stream and before any other operations have been performed on it.
The other three calls are, in effect, simply aliases for calls to setvbuf. The setbuf function is exactly equivalent to the call
setvbuf(stream, buf, buf ? _IOFBF : _IONBF, BUFSIZ);
The setbuffer function is the same, except that the size of the buffer is up to the caller, rather than being determined by the default
BUFSIZ. The setlinebuf function is exactly equivalent to the call:
setvbuf(stream, (char *)NULL, _IOLBF, 0);
RETURN VALUE
The function setvbuf returns 0 on success. It can return any value on failure, but returns nonzero when mode is invalid or the request
cannot be honoured. It may set errno on failure. The other functions are void.
CONFORMING TO
The setbuf and setvbuf functions conform to ANSI X3.159-1989 (``ANSI C'').
BUGS
The setbuffer and setlinebuf functions are not portable to versions of BSD before 4.2BSD, and are available under Linux since libc 4.5.21.
On 4.2BSD and 4.3BSD systems, setbuf always uses a suboptimal buffer size and should be avoided.
You must make sure that both buf and the space it points to still exist by the time stream is closed, which also happens at program termi-
nation.
For example, the following is illegal:
#include <stdio.h>
int main()
{
char buf[BUFSIZ];
setbuf(stdin, buf);
printf("Hello, world!
");
return 0;
}
