+ \begin{funcdesc}{sertdlopenflags}{n}
+ Set the flags that will be used for \code{dlopen()} calls, i.e. when
+ the interpreter loads extension modules. Among other things, this
+ will enable a lazy resolving of symbols when imporing a module, if
+ called as \code{sys.setdlopenflags(0)}. To share symols across
+ extension modules, call as
+ \code{sys.setdlopenflags(dl.RTLD_NOW|dl.RTLD_GLOBAL)}. The symbolic
+ names for the flag modules can be either found in the \refmodule{dl}
+ module, or in the \module{DLFCN} module. If \module{DLFCN} is not
+ available, it can be generated from \code{/usr/include/dlfcn.h} using
+ the \code{h2py} script.
