Copy a string.
Defined in <SDL3/SDL_stdinc.h>
size_t SDL_strlcpy(char *dst, const char *src, size_t maxlen);| char * | dst | The destination buffer. Must not be NULL, and must not overlap with src. | 
| const char * | src | The null-terminated string to copy. Must not be NULL, and must not overlap with dst. | 
| size_t | maxlen | The length (in characters) of the destination buffer. | 
(size_t) Returns the length (in characters, excluding the null terminator) of src.
This function copies up to maxlen - 1 characters from src to dst, then appends a null terminator.
If maxlen is 0, no characters are copied and no null terminator is written.
If you want to copy an UTF-8 string but need to ensure that multi-byte sequences are not truncated, consider using SDL_utf8strlcpy().
It is safe to call this function from any thread.
This function is available since SDL 3.2.0.
