//! \brief Copy a `NUL`-terminated char16-based string to a fixed-size buffer.
|
|
//!
|
|
//! This function behaves identically to `strlcpy()`, but it operates on char16
|
|
//! data instead of `char` data. It copies the `NUL`-terminated string in the
|
|
//! buffer beginning at \a source to the buffer of size \a length at \a
|
|
//! destination, ensuring that the destination buffer is `NUL`-terminated. No
|
|
//! data will be written outside of the \a destination buffer, but if \a length
|
|
//! is smaller than the length of the string at \a source, the string will be
|
|
//! truncated.
|
|
//!
|
|
//! \param[out] destination A pointer to a buffer of at least size \a length
|
|
//! char16 units (not bytes). The string will be copied to this buffer,
|
|
//! possibly with truncation, and `NUL`-terminated. Nothing will be written
|
|
//! following the `NUL` terminator.
|
|
//! \param[in] source A pointer to a `NUL`-terminated string of char16 data. The
|
|
//! `NUL` terminator must be a `NUL` value in a char16 unit, not just a
|
|
//! single `NUL` byte.
|
|
//! \param[in] length The length of the \a destination buffer in char16 units,
|
|
//! not bytes. A maximum of \a `length - 1` char16 units from \a source will
|
|
//! be copied to \a destination.
|
|
//!
|
|
//! \return The length of the \a source string in char16 units, not including
|
|
//! its `NUL` terminator. When truncation occurs, the return value will be
|
|
//! equal to or greater than than the \a length parameter.
