read(,,) & write(,,)

**PankajDS** · 01-09-2008

I came across read & write commands as
len = read(ipf,buf,4096);
write(opf,buf,len);

What is significance of each parameter ?
plz help me...........

For the read() function, do this at the command line:

Code:

man 2 read

Lather, rinse, and repeat for write().

In general, for any function (we'll call her barney() for this example), do this at the command line:

Code:

man -a barney

If the man page for that function is not installed on your system, google for this:

Code:

man barney Linux

Hope this helps.
