    Command:

    fwrite

    
    
    

    SYNOPSIS

           #include <stdio.h>
    
           size_t fread(void *ptr, size_t size, size_t nmemb, FILE *stream);
    
           size_t fwrite(const void *ptr, size_t size, size_t nmemb,
                         FILE *stream);
    
    
    

    DESCRIPTION

           The  function  fread()  reads  nmemb  elements of data, each size bytes
           long, from the stream pointed to by stream, storing them at  the  loca-
           tion given by ptr.
    
           The  function  fwrite()  writes nmemb elements of data, each size bytes
           long, to the stream pointed to by stream, obtaining them from the loca-
           tion given by ptr.
    
           For nonlocking counterparts, see unlocked_stdio(3).
    
    
    

    RETURN VALUE

           On  success,  fread()  and  fwrite() return the number of items read or
           written.  This number equals the number of bytes transferred only  when
           size  is 1.  If an error occurs, or the end of the file is reached, the
           return value is a short item count (or zero).
    
           fread() does not distinguish between end-of-file and error, and callers
           must use feof(3) and ferror(3) to determine which occurred.
