Why can not I see the name of a child process?

Question

Hi,
I implemented a program for my project.
My program has two processes. One is a parent process. Another is a child process.
The parent process forks its child process. The child process is executed by execl() system call.
The program code implemented is followed.
=== abbreviation ===
switch(itmr_forkid = fork()) {
case 0:
RCode = execl("./itmr", "itmr", (char *) 0);
exit(0);
break;
=== abbreviation ===
I executed the program. And then I pressed "ps -ef" on command line.
[stp1ggsn1][user/shlim] ps -ef
UID PID PPID C STIME TTY TIME      CMD
root 29402 29376 38 Mar 06 pts/0 11376:36 ibgfb
root 29403 29402 0 Mar 06 pts/0 0:15
However, why can not I see itmr process name for the child process?
When I executed the program for the parent process and the program for the child process respectively, I can see itmr process name for the child process.
I tried to look for the cause. But I could not find out the answer.
Please, give me your answer. Thank you for your answer in advance.
