Consuming pipe Inputs in Unix

You’d like your application to read pipe inputs, like “ls -la | myGreatApp”? That’s pretty easy:
#include <stdio.h> #include <unistd.h> int main(void) { char input[BUFSIZ]; /* just read it ... */ read(STDIN_FILENO, input, BUFSIZ); /* ... and use it */ puts(input); return(0); }
