Consider the following C program that uses the POSIX API: 'A'; #include #include char valuel = int main() { char value2 = 'A'; pid_t p = fork(); if (p == 0) { write (STDOUT_FILENO, &valuel, 1); write (STDOUT_FILENO, &value2, 1); valuel = value2 = } else { waitpid(p, NULL, 0); valuel = 'C'; value2 = } write (STDOUT_FILENO, &valuel, 1); write(STDOUT_FILENO, &value2, 1); } 'B'; 'B'; 'C'; Given char x 'A';, running write (STDOUT_FILENO, &x, 1) outputs A to stdout. Assume that calls to fork, write, and waitpid do not fail. One possible output of this program is AABBCC. If another output is possible, write another possible output. If no other output is possible, write none
