a simple question...

[Javier Matos]

Hello, I´m a student of computer science and this year I must to do an application using system calls.
We are using linux system calls like "pid_t fork(void)" and other services of the standard POSIX. I want to know if it´s possible to use that system calls in FreeBSD because I prefer to improve my use of freebsd. I will write my application in C and I have freebsd 5.4 with linux compability activated.

Thanks for all!
