WRITE(2)                                             Linux Programmer's Manual                                            WRITE(2)
NAME
       write - write to a file descriptor
SYNOPSIS
       #include <unistd.h>
       ssize_t write(int fd, const void *buf, size_t count);
DESCRIPTION
       write() writes up to count bytes from the buffer starting at buf to the file referred to by the file descriptor fd.
       The number of bytes written may be less than count if, for example, there is insufficient space on the underlying physical
       medium, or the RLIMIT_FSIZE resource limit is encountered (see setrlimit(2)), or the call was interrupted by a signal han‐
       dler after having written less than count bytes. (See also pipe(7).)
       For a seekable file (i.e., one to which lseek(2) may be applied, for example, a regular file) writing takes place at the
       file offset, and the file offset is incremented by the number of bytes actually written. If the file was open(2)ed with
       O_APPEND, the file offset is first set to the end of the file before writing. The adjustment of the file offset and the
       write operation are performed as an atomic step.
       POSIX requires that a read(2) that can be proved to occur after a write() has returned will return the new data. Note that
       not all filesystems are POSIX conforming.
       According to POSIX.1, if count is greater than SSIZE_MAX, the result is implementation-defined; see NOTES for the upper
       limit on Linux.
RETURN VALUE
       On success, the number of bytes written is returned (zero indicates nothing was written). It is not an error if this num‐
       ber is smaller than the number of bytes requested; this may happen for example because the disk device was filled. See
       also NOTES.
       On error, -1 is returned, and errno is set appropriately.
       If count is zero and fd refers to a regular file, then write() may return a failure status if one of the errors below is
       detected. If no errors are detected, or error detection is not performed, 0 will be returned without causing any other ef‐
       fect. If count is zero and fd refers to a file other than a regular file, the results are not specified.

Accepted Answer

write() takes as input 3 parameters

Accepted Answer

To compile a C program with write(), unistd.h must be included

Accepted Answer

write() is a system call

Answer

Written bytes are always placed at the beginning of a file

Answer

When write() returns less than "count", an error occurred in the system

Answer

write() always returns the number of written bytes
