Except for shl_get and shl_gethandle, all these routines are thread
safe.
These routines are described in the shl_load(3x) man page.
The dlopen Routines Summary
The dlopen family of shared library management routines is available
only for the 64-bit linker.
The dlopen family of routines use Unix SVR4 shared library
mechanisms.

shl_definesym Adds a new symbol to the global shared library
symbol table.
shl_getsymbols Returns a list of symbols in a shared library.
shl_unload and
cxxshl_load
Unload a shared library and a C++ shared
library, respectively. They have the same
syntax.
