Luna::strnlen

template <typename _CharT>
usize strnlen(const _CharT *str, usize max_chars)

Computes the length (number of characters) of the specified string by searching for the first null character in the string. The search process stops after reading max_chars characters.

Parameters

• in str

  The string to be examined.

• in max_chars

  The maximum number of characters to examine, including the null terminator.

Return value

Returns the length of the string. The length does not include the null terminator. Returns 0 if s is nullptr. Returns max_chars if the null character is not found in the first max_chars characters of s.
