Function Documentation

void hold_to (  int  dt  )

Delay the current process by 'dt' time units. Parameters: dt  time units

void pearlwaiting (  int  reply_wait  )

void pearlsend (  int  dest, int  method, int *  sp, int  len )

Send a message to 'dest'. Mask contains the identifier of the remote method. The contents of the message is on the stack, starting at the position 'sp' points to. 'Len' is the length of the message. If the message is sent, first a check if the destination expects the messages is done. If so, the message is written on the destination's stack. If not, the message is put in the destination's message queue. Parameters: dest  method  sp  starting position len  length of message

int receive_time (  int *  mask, int  dt, int *  sp )

Delay process for 'dt' units and check if there are messages in its message queue. If so, remove process from process table again. Parameters: mask  dt  time units sp  Returns:

int pearlreceive (  int *  mask, int *  sp )

Look in the message queue of the pearl_current process if there are messages. If so, check if one of them is expected by the process. If so, duplicate message onto processes stack. Parameters: mask  sp  Returns:

char* stateString (  int  state  )

void statistics (  int  procnr  )

Put 'statistics' method-label in process's stack and schedule process one pearl_time. Parameters: procnr  Returns:

int catcherfunc (   )

void schedule (   )

Schedule processes from the schedule queue as long as there are processes to be scheduled. Returns:
