# Other possible defines:
# To use poll(2) instead of select(2) for events checking:
# DEFINES += -DUSE_POLL
# You may prefer to use select for applications that have many threads
# using one file descriptor, and poll for applications that have many
# different file descriptors.  With USE_POLL poll() is called with at
# least one pollfd per I/O-blocked thread, so 1000 threads sharing one
# descriptor will poll 1000 identical pollfds and select would be more
# efficient.  But if the threads all use different descriptors poll()
# may be better depending on your operating system's implementation of
# poll and select.  Really, it's up to you.  Oh, and on some platforms
# poll() fails with more than a few dozen descriptors.
#
# Some platforms allow to define FD_SETSIZE (if select() is used), e.g.:
# DEFINES += -DFD_SETSIZE=4096
#
# To use malloc(3) instead of mmap(2) for stack allocation:
# DEFINES += -DMALLOC_STACK
#
# To provision more than the default 16 thread-specific-data keys
# (but not too many!):
# DEFINES += -DST_KEYS_MAX=<n>
#
# To start with more than the default 64 initial pollfd slots
# (but the table grows dynamically anyway):
# DEFINES += -DST_MIN_POLLFDS_SIZE=<n>
#
# Note that you can also add these defines by specifying them as
# make/gmake arguments (without editing this Makefile). For example:
#
# make EXTRA_CFLAGS=-DUSE_POLL <target>
#
# (replace make with gmake if needed).
#
# You can also modify the default selection of an alternative event
# notification mechanism. E.g., to enable kqueue(2) support (if it's not
# enabled by default):
#
# gmake EXTRA_CFLAGS=-DMD_HAVE_KQUEUE <target>
#
# or to disable default epoll(4) support:
#
# make EXTRA_CFLAGS=-UMD_HAVE_EPOLL <target>
