SDL_strlcpy - Man Page

#include <SDL3/SDL_stdinc.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.
