FWRITE(3C)							    FWRITE(3C)

       fwrite - binary output

       #include <stdio.h>

       size_t fwrite(const void *ptr, size_t size, size_t nitems, FILE *stream);

       The  fwrite()  function writes, from the array pointed to by ptr, up to
       nitems elements whose size is specified by size, to the stream  pointed
       to  by  stream.	For  each object, size calls are made to the fputc(3C)
       function, taking the values (in order) from an array of	unsigned  char
       exactly	overlaying  the	 object.  The  file-position indicator for the
       stream (if defined) is advanced by the  number  of  bytes  successfully
       written.	 If  an error occurs, the resulting value of the file-position
       indicator for the stream is unspecified.

       The st_ctime and st_mtime fields of the file will be marked for	update
       between	the  successful	 execution of fwrite() and the next successful
       completion of a call to fflush(3C) or fclose(3C) on the same stream  or
       a call to exit(2) or abort(3C).

       The fwrite() function returns the number of elements successfully writ‐
       ten, which might be less than nitems if a write error  is  encountered.
       If  size or nitems is 0, fwrite() returns 0 and the state of the stream
       remains unchanged. Otherwise, if a write error occurs, the error	 indi‐
       cator for the stream is set and errno is set to indicate the error.

       Refer to fputc(3C).

       Because	of  possible  differences in element length and byte ordering,
       files written using fwrite() are	 application-dependent,	 and  possibly
       cannot  be  read	 using	fread(3C) by a different application or by the
       same application on a different processor.
