Predefined Functions
Predefined functions assist the developer in debugging applications and in creating his own functions. Predefined functions cannot be deleted or modified.
The following table lists all predefined debugging functions.
| Return | Name | Parameter | Description |
|---|---|---|---|
| double | __acos | (double) | Calculates the arc cosine. |
| double | __asin | (double) | Calculates the arc sine. |
| double | __atan | (double) | Calculates the arc tangent. |
| double | __cos | (double) | Calculates the cosine. |
| double | __exp | (double) | Calculates the exponential. |
| double | __log | (double) | Calculates the natural logarithm. |
| double | __log10 | (double) | Calculates the common logarithm. |
| double | __sin | (double) | Calculates the sine. |
| double | __sqrt | (double) | Calculates the square root. |
| double | __tan | (double) | Calculates the tangent. |
| uchar | _RBYTE | (address) | Read a char from the memory address. |
| uint | _RWORD | (address) | Reads a short int from the memory address. |
| ulong | _RDWORD | (address) | Reads a long from the memory address. |
| float | _RFLOAT | (address) | Reads a float from the memory address. |
| double | _RDOUBLE | (address) | Reads a double from the memory address. |
| int | _TaskRunning_ | (ulong func_address) | Checks if the specified task function is the currently running task. Available only if a DLL for RTX Kernel Awareness is used. |
| double | _sleep_ | (ulong milli_seconds) | Delays execution for milli seconds. |
| void | _WBYTE | (address, uchar val) | Writes a char to the memory address. |
| void | _WWORD | (address, uint val) | Write a short int to the memory address. |
| void | _WDWORD | (address, ulong val) | Writes a long to the memory address. |
| void | _WFLOAT | (address, float val) | Writes a float o the memory address. |
| void | _WDOUBLE | (address, double val) | Writes a double to the memory address. |
| void | exec | ("command_string") | Executes the debug command. |
| double | getdbl | ("prompt_string") | Prompts the user to enter a double. |
| int | getint | ("prompt_string") | Prompts the user to enter an integer. |
| long | getlong | ("prompt_string") | Prompts the user to enter a long number. |
| void | memset | (start_addr, len, value) | Fills the memory starting at start_addr and the length len with the value. |
| void | printf | ("string", ...) | Works like the ANSI-C printf function. |
| int | rand | (int seed) | Returns a random number in the range 0 to 32767. |
| void | rwatch | (ulong address) | Delays the execution of a signal function until a read-access event occurs on address. |
| void | swatch | (float seconds) | Delays the execution of a signal function for seconds. |
| void | twatch | (ulong states) | Delays the execution of a signal function for number of CPU states. |
| void | wwatch | (ulong address) | Delays the execution of a signal function until a write-access event occurs on address. |
