NAME¶

SDL_strnlen - This works exactly like strnlen() but doesn't require access to a C runtime.

SYNOPSIS¶

#include <SDL3/SDL_stdinc.h>

size_t SDL_strnlen(const char *str, size_t maxlen);

DESCRIPTION¶

Counts up to a maximum of maxlen bytes in str, excluding the null terminator.

If you need the length of a UTF-8 string, consider using SDL_utf8strnlen().

FUNCTION PARAMETERS¶

str

The null-terminated string to read. Must not be NULL.

maxlen

The maximum amount of bytes to count.

RETURN VALUE¶

Returns the length (in bytes, excluding the null terminator) of src but never more than maxlen.

THREAD SAFETY¶

It is safe to call this function from any thread.

AVAILABILITY¶

This function is available since SDL 3.2.0.
