This is a tiny printf implementation.
Absolutely NO dependencies are required, printf.c brings all necessary routines, even its own fast ftoa (floating point), ntoa (decimal) conversion.
Usage is like the according stdio.h library version:
int printf(const char* format, ...);A format specifier follows this prototype: %[flags][width][.precision][length]type
The following format specifiers are supported:
| Type | Output |
|---|---|
| d or i | Signed decimal integer |
| u | Unsigned decimal integer |
| o | Unsigned octal |
| x | Unsigned hexadecimal integer (lowercase) |
| X | Unsigned hexadecimal integer (uppercase) |
| c | Single character |
| s | String of characters |
| p | Pointer address |
| % | A % followed by another % character will write a single % |
| Flags | Description |
|---|---|
| (space) | If no sign is going to be written, a blank space is inserted before the value. |
| # | Used with o, b, x or X specifiers the value is preceded with 0, 0b, 0x or 0X respectively for values different than zero. Used with f, F it forces the written output to contain a decimal point even if no more digits follow. By default, if no digits follow, no decimal point is written. |
