Examine the code in process-fork-1.cpp. What is the value returned by the call to the fork() function if an error occurs and the OS is unable to create a child process?

#include #include

int main() { pid_t id = fork();

if(id == -1) { std::cout << "Error creating process "; } else if (id == 0) { std::cout << "I am a child process! "; } else { std::cout << "I just became a parent! "; }

return 0; }
