The evbuffer_remove() function copies data from the front of an evbuffer into an array of char, and removes the data from the buffer. This function behaves the same, but does not remove the data. This behavior can be handy for lots of protocols, where you want the evbuffer to accumulate data until a complete record has arrived. Lots of people have asked for a function more or less like this, and though it isn't too hard to code one from evbuffer_peek(), it is apparently annoying to do it in every app you write. The evbuffer_peek() function is significantly faster, but it requires that the user be able to handle data in separate extents. This patch also reimplements evbufer_remove() as evbuffer_copyout() followed by evbuffer_drain(). I am reasonably confident that this won't be a performance hit: the memcpy() overhead should dominate the cost of walking the list an extra time.
0. BUILDING AND INSTALLATION (Briefly)
$ ./configure
$ make
$ make verify # (optional)
$ sudo make install
1. BUILDING AND INSTALLATION (In Depth)
To build libevent, type
$ ./configure && make
(If you got libevent from the git repository, you will
first need to run the included "autogen.sh" script in order to
generate the configure script.)
Install as root via
# make install
You can run the regression tests by running
$ make verify
Before, reporting any problems, please run the regression tests.
To enable the low-level tracing build the library as:
CFLAGS=-DUSE_DEBUG ./configure [...]
Standard configure flags should work. In particular, see:
--disable-shared Only build static libraries
--prefix Install all files relative to this directory.
The configure script also supports the following flags:
--enable-gcc-warnings Enable extra compiler checking with GCC.
--disable-malloc-replacement
Don't let applications replace our memory
management functions
--disable-openssl Disable support for OpenSSL encryption.
--disable-thread-support Don't support multithreaded environments.
