NAME
SDL_itoa - Convert an integer into a string.
HEADER FILE
Defined in SDL3/SDL_stdinc.h
SYNOPSIS
#include "SDL3/SDL.h"
char * SDL_itoa(int value, char *str, int radix);
DESCRIPTION
This requires a radix to specified for string format. Specifying 10 produces a decimal number, 16 hexidecimal, etc. Must be in the range of 2 to 36.
Note that this function will overflow a buffer if str is not large enough to hold the output! It may be safer to use SDL_snprintf
to clamp output, or SDL_asprintf
to allocate a buffer. Otherwise, it doesn't hurt to allocate much more space than you expect to use (and don't forget possible negative signs, null terminator bytes, etc).
FUNCTION PARAMETERS
- value
-

- str
-
the buffer to write the string into.
- radix
-
the radix to use for string generation.
RETURN VALUE
Returns str .
THREAD SAFETY
It is safe to call this function from any thread.
AVAILABILITY
This function is available since SDL 3.2.0.
