# Error Handling

# bool pkpy_clear_error(pkpy_vm*, char** message)

  • If a method returns false, call the pkpy_clear_error method to check the error and clear it
  • If pkpy_clear_error returns false, it means that no error was set, and it takes no action
  • If pkpy_clear_error returns true, it means there was an error and it was cleared. It will provide a string summary of the error in the message parameter (if it is not NULL) If null is passed in as message, and it will just print the message to stderr.
  • You are responsible for freeing message.

# bool pkpy_check_error(pkpy_vm*)

Return true if the vm is currently in an error state.

# bool pkpy_error(pkpy_vm*, const char* name, const char* message)

Set the error state of the vm. It is almost equivalent to raise in python.
