Re: POSIX thread question

I tried the following command, it works:
gcc -pthread -o threadapp threadapp.c

My book suggests the following:
gcc -pthread threadapp.c -o threadapp -lpthread

What is the different? Which on is better?

The first is better. The first will work whether or not there happens
to be a library called 'libpthread' that is needed for POSIX pthreads.
The second may fail or do the wrong thing if such a library does not
exist, is not needed, or does the wrong thing.
