Function Documentation

PmReturn_t interp_addThread ( pPmFunc_t pfunc )

Creates a thread object and adds it to the queue of threads to be executed while interpret() is running.

The given obj may be a function, module, or class. Creates a frame for the given function.

Parameters:

pfunc Ptr to function to be executed as a thread.

PmReturn_t interp_reschedule ( void )

Selects a thread to run and changes the VM internal variables to let the switch-loop execute the chosen one in the next iteration.

For the moment the algorithm is primitive and will change the thread each time it is called in a round-robin fashion.

Definition at line 2212 of file interp.c.

void interp_setRescheduleFlag ( uint8_t boolean )

Sets the reschedule flag.

Parameters:

boolean Reschedule on next occasion if boolean is true; clear the flag otherwise.

Definition at line 2264 of file interp.c.

PmReturn_t interpret ( const uint8_t returnOnNoThreads )

Interprets the available threads.

Does not return.

Parameters:

returnOnNoThreads Loop forever if 0, exit with status if no more threads left.

Returns:: Return status if called with returnOnNoThreads != 0, will not return otherwise.
