Hi
Could anyone clarify on the types of buffers used by a program?
For eg:
I have a C program that reads from a stdin to stdout.
What are the buffers involved here? I'm aware that there are 2.
One provided by the kernel on which a user don't have any control.
One provided with standard streams namely stdout, stdin and stderr. Each having a separate buffer.

reading a file that doesn't exist
Hi,
I have got a small program that prints the contents of files using the system call - read.
...Code:unsigned char buffer[8]; size_t offset=0; size_t bytes_read; int i; int fd = open(argv[1], O_RDONLY); do{ bytes_read = read(fd, buffer, sizeof(buffer)); printf("0x%06x : ", offset); for(i=0; i<bytes_read;
