FREAD(3S)FREAD(3S)NAME
fread, fwrite - buffered binary input/output
SYNOPSIS
#include <stdio.h>
fread(ptr, sizeof(*ptr), nitems, stream)
FILE *stream;
fwrite(ptr, sizeof(*ptr), nitems, stream)
FILE *stream;
DESCRIPTION
Fread reads, into a block beginning at ptr, nitems of data of the type of *ptr from the named input stream. It returns the number of items
actually read.
If stream is stdin and the standard output is line buffered, then any partial output line will be flushed before any call to read(2) to
satisfy the fread.
Fwrite appends at most nitems of data of the type of *ptr beginning at ptr to the named output stream. It returns the number of items
actually written.
SEE ALSO read(2), write(2), fopen(3S), getc(3S), putc(3S), gets(3S), puts(3S), printf(3S), scanf(3S)DIAGNOSTICS
Fread and fwrite return 0 upon end of file or error.

hi everybody!
i need to read a specific line from a text file using C. can any one suggest how to do it.
i m aware abt fread(), fwrite(), fseek()... but using these allows the pointer to be moved 1 character at a time. Is there a way i could jump directly to a line if i know the line number?... (4 Replies)
Original code used fwrite instead of putc.
What is expected is that the destination file will be written to. Instead I end up with a zero length file. I'm sure there is something simple I'm missing.
tia.

what is the difference between
fopen and open
fread and read
fwrite and write
open and create
why this much of functions for the i/o when everything does the same...?
What is their major difference?
In which case, which is the best to use.

hi guys.
can we use fread and fwrite with pipes to write data more than PIPE_BUF atomically since they lock FILE object until I/O operation finish? (1 Reply)
Hello,
I am trying to read a text file into linked list, but always got the first and last records wrong.
1) The problem looks related to the initialization of the node temp with malloc(), but could not figure it out. No error/warning at compiling, though.
2) The output file is empty,... (10 Replies)
