<div>
FILE *f;<br />
f = fopen(&quot;myFile&quot;,&quot;w&quot;); &nbsp;// Open the file for writing<br />
fwrite(someBuff,1,6,f); &nbsp; &nbsp;// write the first 6 bytes pointed to by someBuff<br />
fclose(f);<br />
<br />
Some File I/O function to look at are:<br />
fopen()<br />
fclose()<br />
fread()<br />
fwrite()<br />
fprintf()<br />
<br />
These function are available on all platforms as well.

How can we output fixed no. of bytes to a file in C ? e.g 'long int' datatype is 8 bytes, how can we output only 6 bytes to a &nbsp;file ?<br />
What are the formatted File I/O functions avaialble when programming on UNIX in C ?

File I/O in C

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
