about Posix Threads

["Lejanson C. Go" <lejanson@ntsp.nec.co.jp>]

hello everyone. i am new here. i just would like to ask some
questions regarding posix threads and i hope someone could help
me.

i made a pthread program and i am quite puzzled why my program
spawns 4 threads.. when i view it in linux console.

i used 'ps -ax | grep myprog' command to get the processes for
my application and to my surprise it spawns 4 threads.. when i
only expected 3.. one for main, one for event, and one for recvdata.

spawnXXXXXX functions create new threads..

i really need ur help. can anyone tell me why this occur?

thanks a lot...
