/* SYNOPSIS
/* #include <load_lib.h>
/*
/* void load_library_symbols(const char *, LIB_FN *, LIB_DP *);
/* const char *libname;

/* DESCRIPTION
/* load_library_symbols() loads the specified shared object
/* and looks up the function or data pointers for the specified
/* symbols. All errors are fatal.
/*
/* Arguments:
/* .IP libname
/* shared-library pathname.
/* .IP libfuncs
/* Array of LIB_FN structures. The last name member must be null.
/* .IP libdata
/* Array of LIB_DP structures. The last name member must be null.
