How to port LCK_pend( ) with timeout parameter to SYS/BIOS?

Hi,

Now I want to replace the following LCK_pend( ) in SYS/BIOS:

if( FALSE == LCK_pend( lock_hdl, 0xFFFFFFFF ) )

According to SPRAAS7, the "LCK" module is to replaced by the "GateMutex" module.  

But GateMutex doesn't take the timeout paremeter.

Should I use SYS/BIOS 6 legacy module?

since I have already created a .cfg file for new SYS/BIOS project,  What's the step to integrate the LCK module based on the cfg file?

Thanks in advance!
