Available on crate feature dep_sdl3 only.
Expand description

Search a string, up to n bytes, for the first instance of a specific substring.

The search ends once it finds the requested substring, or a null terminator byte to end the string, or maxlen bytes have been examined. It is possible to use this function on a string without a null terminator.

Note that this looks for strings of bytes, not characters, so it’s legal to search for malformed and incomplete UTF-8 sequences.

§Parameters

  • haystack: the string to search. Must not be NULL.
  • needle: the string to search for. Must not be NULL.
  • maxlen: the maximum number of bytes to search in haystack.

§Return value

Returns a pointer to the first instance of needle in the string, or NULL if not found.

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
