SDL_strlcpy - Copy a string.

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

size_t SDL_strlcpy(char *dst, const char *src, size_t maxlen);

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 ().

	dst		The destination buffer. Must not be NULL, and must not overlap with src .
	src		The null-terminated string to copy. Must not be NULL, and must not overlap with dst .
	maxlen		The length (in characters) of the destination buffer.

Returns the length (in characters, excluding the null terminator) of src .

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
