Count Number Of Threads in a Process

I am trying to find out that how many number of threads are currently running or in any other state which is created by POSIX standard in a process.
First I have defined a variable called proc_var of type proc defined in sys/proc.h.Next I open up the dir /proc and per directory wise I do an ioctl operation with cmd type PIOCPSINFO and target as address space of proc_var. But when I print the value of the member variable p_lwpcnt of proc_var ( i am not sure wether i am reffering to the correct one ) , i get output '6488064' as its value.I found out that the process is a user created one and the code creates only four threads.
Kindly guide me how to find the correct number Threads and its details, currently executing in a process.
