Very basic error printing code that allows you to print in color, even on Windows

Logging

This piece of code allows you to print errors in color to help them stand out, even on Windows.

Usage

• Include logging.h
• Add logging.c to your source file list or otherwise add it to your compiler setup
• Call log_error(), ANSI color codes will be automatically enabled if necessary

log_error() functions identically to printf(), except that you need to pass in an enum value to indicate what color your message should be prefixed with.

Examples:

#include "logging.h"
#include "malloc.h"

int main() {
    unsigned int size = 1024;
    char* buffer = malloc(size);
    if (buffer == NULL)
    {
      log_error(CRITICAL, "Couldn't allocate the buffer with size %d!\n", size);
    }
    else
    {
      log_error(DEBUG, "Allocated %d bytes of memory.\n", size);
      unsigned int result = some_function(buffer);
      if (result > 0)
      {
        log_error(WARNING, "Potential error operating on a buffer in main()\n");
      }
      unsigned int texture_count = 10;
      unsigned int model_count = 5;
      log_error(INFO, "Reporting to the user: found %d textures and %d models in this file.\n", texture_count, model_count);
      free(buffer);
      log_error(DEBUG, "Freed %d bytes of memory.\n", size);
    }
    return 0;
}
