Does Object Manager lock objects, such as arrays, when writing to them?
There is no write locking on scalar objects. The mode flag on the OMfind_subobj API call should serve this purpose, but is not. The mode flag on Object Manager array routines (such as OMret_array_ptr) does do write locking. If the mode flag is set to WR (write) or RW (read-write), the Object Manager will not let you write to the array. The array is unlocked when an ARRfree is executed on it. However, since AVS/Express is single threaded, this won’t generally be an issue. Typically, a module executes, gets the array, frees it when it’s done and then returns. Only then does the next module execute.
