A pipe is two or more commands separated by pipe char '|'. That tells the shell to arrange for the output of the preceding command to be passed as input to the following command. Example : ls -l | prThe output for a command ls is the standard input of pr. When a sequence of commands are combined using pipe, then it is called pipeline.

The header to this question is wrong. This is not a unix command it should be titled "C library function to store data in a file".

The answer would then be (a) fwrite.

fwrite is not operating system specific and will work the same on Unix or Windows.
