C library for debug printing with GCC.
Use the DBG_PRINTF_X macro for printing, where X is the debug level.
These levels and their coloured outputs are as follows:
| Level | Colour |
|---|---|
| Debug | Green |
| Trace | White |
| Warning | Yellow |
| Error | Red |
Finally, you will need to implement the int debug_print_callback(char* debugMessage, unsigned int length).
This callback function is called in the debug print functions so that the user can decide where to and how to print the debug messages.
See the debug_print.h file for more info.
- Define
DBG_PRINT_ENABLEDto 1/0 enable/disable debug printing. - Define
DGB_PRINT_BUFFER_SIZEto set the debug print message buffer size. - Define
DBG_PRINT_ENABLE_TIMESTAMPto 1/0 to include/exclude timestamps in debug messages.- NOTE: You must implement
time_t debug_print_get_timestamp(void)which returns the timestamp from the system.
- NOTE: You must implement
The colour of the output depends on the used debug level but message format stays the same.
The output format is [<filename>:<function name>():<line number>]: <message>.
An example output would be: [main.c:main():13]: Initializing.
