# - check_nonblocking_socket_support()
#
# Check for how to set a socket to non-blocking state. There seems to exist
# four known different ways, with the one used almost everywhere being POSIX
# and XPG3, while the other different ways for different systems (old BSD,
# Windows and Amiga).
#
# One of the following variables will be set indicating the supported
# method (if any):
# HAVE_O_NONBLOCK
# HAVE_FIONBIO
# HAVE_IOCTLSOCKET
# HAVE_IOCTLSOCKET_CASE
# HAVE_SO_NONBLOCK
# HAVE_DISABLED_NONBLOCKING
#
# The following variables may be set before calling this macro to
# modify the way the check is run:
#
# CMAKE_REQUIRED_FLAGS = string of compile command line flags
# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
# CMAKE_REQUIRED_INCLUDES = list of include directories
# CMAKE_REQUIRED_LIBRARIES = list of libraries to link
#
macro(check_nonblocking_socket_support)
# There are two known platforms (AIX 3.x and SunOS 4.1.x) where the
# O_NONBLOCK define is found but does not work.
