new switch -F (do not fork) added automatic forking if -F not specified

opened 0.98 development removed driver-specific signal-handlers added 'quit'-function to driver structure added global signal-handler

moved delay loops to udelay.c renamed -d (debugging) switch to -v (verbose) new switch -d to calibrate delay loop 'Delay' entry for HD44780 back again delay loops will not calibrate automatically, because this will fail with hich CPU load

added '-d' (debugging) switch added several debugging messages removed config entry 'Delay' for HD44780 driver delay loop for HD44780 will be calibrated automatically

* * Revision 1.7 2005/01/18 06:30:23 reinelt * added (C) to all copyright statements * * Revision 1.6 2004/06/26 12:05:00 reinelt * * uh-oh... the last CVS log message messed up things a lot... * * Revision 1.5 2004/06/26 09:27:21 reinelt * * added '-W' to CFLAGS * changed all C++ comments to C ones * cleaned up a lot of signed/unsigned mistakes * * Revision 1.4 2004/03/06 20:31:16 reinelt * Complete rewrite of the evaluator to get rid of the code * from mark Morley (because of license issues). * The new Evaluator does a pre-compile of expressions, and * stores them in trees. Therefore it should be reasonable faster... * * Revision 1.3 2004/03/03 03:47:04 reinelt * big patch from Martin Hejl: * - use qprintf() where appropriate * - save CPU cycles on gettimeofday() * - add quit() functions to free allocated memory * - fixed lots of memory leaks * * Revision 1.2 2004/01/29 04:40:02 reinelt * every .c file includes "config.h" now * * Revision 1.1 2003/12/19 05:50:34 reinelt * added plugin_math.c and plugin_string.c * */ /* * exported functions: * * int plugin_init_math (void) * adds some handy constants and functions * */ #include "config.h" #include <stdlib.h> #include <stdio.h> #include <math.h> #include "debug.h" #include "plugin.h" static void my_sqrt(RESULT * result, RESULT * arg1) { double value = sqrt(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_exp(RESULT * result, RESULT * arg1) { double value = exp(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_ln(RESULT * result, RESULT * arg1) { double value = log(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_log(RESULT * result, RESULT * arg1) { double value = log10(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_sin(RESULT * result, RESULT * arg1) { double value = sin(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_cos(RESULT * result, RESULT * arg1) { double value = cos(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_tan(RESULT * result, RESULT * arg1) { double value = tan(R2N(arg1)); SetResult(&result, R_NUMBER, &value); } static void my_min(RESULT * result, RESULT * arg1, RESULT * arg2) { double a1 = R2N(arg1); double a2 = R2N(arg2); double value = a1 < a2 ? a1 : a2; SetResult(&result, R_NUMBER, &value); } static void my_max(RESULT * result, RESULT * arg1, RESULT * arg2) { double a1 = R2N(arg1); double a2 = R2N(arg2); double value = a1 > a2 ? a1 : a2; SetResult(&result, R_NUMBER, &value); } static void my_floor(RESULT * result, RESULT * arg) { double value = floor(R2N(arg)); SetResult(&result, R_NUMBER, &value); } static void my_ceil(RESULT * result, RESULT * arg) { double value = ceil(R2N(arg)); SetResult(&result, R_NUMBER, &value); } int plugin_init_math(void) { /* set some handy constants */ SetVariableNumeric("Pi", M_PI); SetVariableNumeric("e", M_E); /* register some basic math functions */ AddFunction("sqrt", 1, my_sqrt); AddFunction("exp", 1, my_exp); AddFunction("ln", 1, my_ln); AddFunction("log", 1, my_log); AddFunction("sin", 1, my_sin); AddFunction("cos", 1, my_cos); AddFunction("tan", 1, my_tan); /* min, max */ AddFunction("min", 2, my_min); AddFunction("max", 2, my_max); /* floor, ceil */ AddFunction("floor", 1, my_floor); AddFunction("ceil", 1, my_ceil); return 0; } void plugin_exit_math(void) { }
