dup2 to redirect stdout and stderr to another file descriptor

i have a call like this.

int fd[2];
pipe(fd)

and then

dup2(fd[WRITE],STDOUT_FILENO)

is there a way to use the dup call to duplicate both 1 and 2 to fd[WRITE]?

Just repeat this operation for stderr.

dup2(fd[WRITE], STDOUT_FILENO);
dup2(fd[WRITE], STDERR_FILENO);
