int SU_initialize(int argc, char *argv)
In applications built with --userhook,
SU_initialize() is called by the main program before
SP_initialize(). Its purpose is to call interface functions,
which must be called before
SP_initialize(). It is not
meaningful to specify this option if --main=user or
--main=none is given.
Zero on success, and nonzero otherwise. If a non-zero value is returned, the application system exits with the return value as error code.
