| 23 | * \note This function has the similar input argument format as |
| 24 | * the 'printf' function. But it supports only some basic |
| 25 | * formats like 'sdicpuxX' and '%'. It will output |
| 26 | * "[Unsupported Tag]" when none of the above formats match |
| 27 | * |
| 28 | * \details The following output formats are supported. |
| 29 | * %s - string |
| 30 | * %d - decimal signed integer (same for %i) |
| 31 | * %u - decimal unsigned integer |
| 32 | * %x - hex in lowercase |
| 33 | * %X - hex in uppercase |
| 34 | * %p - hex address of a pointer in lowercase |
| 35 | * %c - character |
| 36 | * %% - the '%' symbol |
