The `MaximumLength` field of the structure must be set to the length, in bytes, of the buffer.<br /><br /> **Universal C Runtime (UCRT)**<br />There is a known issue in the UCRT that is currently maintained for compatibility. Like the **`S`** specifier, the **`Z`** specifier without a size modifier prefix refers to a `UNICODE_STRING` when using a narrow printing function (like `printf`) and an `ANSI_STRING` when using a wide printing function (like `wprintf`).<br /> Instead of **`Z`**, use **`hZ`** to specify an `ANSI_STRING`. **`wZ`** (or **`lZ`**) can still be used to specify a `UNICODE_STRING`. <br /><br />Typically, the **`Z`** type character is used only in driver debugging functions that use a conversion specification, such as `dbgPrint` and `kdPrint`. |
 
 In Visual Studio 2015 and later versions, if the argument that corresponds to a floating-point conversion specifier (**`a`**, **`A`**, **`e`**, **`E`**, **`f`**, **`F`**, **`g`**, **`G`**) is infinite, indefinite, or NaN, the formatted output conforms to the C99 standard.

 ## Remarks
 
-If a set bit is found, the bit position of the first set bit found is returned in the first parameter. If no set bit is found, 0 is returned; otherwise, 1 is returned.
+If a set bit is found, the bit position of the first set bit is written to the address specified in the first parameter and the function returns 1. If no bit is found, the function returns 0 and the value written to the address in the first parameter is undefined.
