Then I've learned emcas, and now I use both editors --- the first available on the machine that I'm working on --- also emacs requires a lot of configurations, but is my primary editor on my FreeBSD boxes. > > > > So my question is primarily, does getc use the read system call > > > eventually? > > > > No, certainly not.

Setting up development environment
Hello, Is there any official way to setup a development environment for FreeBSD. I mean, I want to contribute with FreeBSD development.

No, if_ppp requires other headers, I'm far from my BSD system,
but you must look which header you must include before the if_ppp
hreader.

strange pthread keys behavior
Hello,
I'm coding with pthreads, but the behavior of pthread_key_delete
is strange. When I use pthread_key_delete, and I do not wait for the
automatic deallocation of thread specific data, I receive a strange
warning:
Thread 8053800 has exited with leftover thread-specific data after \
4 destructor iterations
¿Is this a mistake in the code or a standard warning in FreeBSD
pthreads?
The code bellow can be compiled with and do not use the
pthread_key_delete routine:
gcc -Wall -Wextra -pthread -lpthread -o key key.c
But if pthread_key_delete is used, compiling the code with:
gcc -Wall -Wextra -DPTHR_WARNS -pthread -lpthread -o key key.c
I get warning message...

If you need strstr(3) in your project is allready defined
in libkern. The implementation is identical, but using the
__DECONST macro.
Take a look in /usr/src/sys/libkern/strstr.c for the function
definition and /usr/src/sys/geom/label/g_label.c for usage.
The function prototype is defined in sys/libkern.h

Do not use the strip command.

Which branch?
Hello, My computer is running with FreeBSD 5.4-STABLE. I've tried updating the source tree with RELENG_5, but I get some compile time errors. Is the RELENG_5 branch abandoned? Also, I must download the RELENG_6 branch (6-STABLE) and contribute to this branch?. Thanks...
