write write on a file (write = 4.)

char *buffer; A file descriptor is a word returned from
a successful or call. is the address of contiguous bytes
which are written on the output file. The number of
characters actually written is returned (in r0). It should
be regarded as an error if this is not the same as
requested. Writes which are multiples of 512 characters long
and begin on a 512-byte boundary in the file are more
efficient than any others. creat (II), open (II), pipe (II)
The error bit (c-bit) is set on an error: bad descriptor,
buffer address, or count; physical I/O errors. From C, a
returned value of 1 indicates an error.
