No, the parent gets back the PID of the child process (or -1 if there
is a failed fork), and the child process will return 0.
from the fork(2) man page:
On success, the PID of the child process is returned in the parent’s
thread of execution, and a 0 is returned in the child’s thread of exe-
cution. On failure, a -1 will be returned in the parent’s context, no
child process will be created, and errno will be set appropriately.
