StringCchPrintf_lW function (strsafe.h)
Writes formatted data to the specified string. The size of the destination buffer is provided to the function to ensure that it does not write past the end of this buffer.
StringCchPrintf_l is similar to StringCchPrintf but includes a parameter for locale information.
Syntax
STRSAFEAPI StringCchPrintf_lW(
[out] STRSAFE_LPWSTR pszDest,
[in] size_t cchDest,
[in] _Printf_format_string_params_(2)STRSAFE_LPCWSTR pszFormat,
[in] _locale_t locale,
...
);
Parameters
[out] pszDest
The destination buffer, which receives the formatted, null-terminated string created from pszFormat and its arguments.
[in] cchDest
The size of the destination buffer, in characters. This value must be sufficiently large to accommodate the final formatted string plus 1 to account for the terminating null character. The maximum number of characters allowed is STRSAFE_MAX_CCH.
[in] pszFormat
The format string. This string must be null-terminated. For more information, see Format Specification Syntax.
[in] locale
The locale object. For more information, see _create_locale.
...
The arguments to be inserted into the pszFormat string.
Return value
This function can return one of the following values. It is strongly recommended that you use the SUCCEEDED and FAILED macros to test the return value of this function.
Return code | Description |
---|---|
|
There was sufficient space for the result to be copied to pszDest without truncation, and the buffer is null-terminated. |
|
The value in cchDest is either 0 or larger than STRSAFE_MAX_CCH. |
|
The copy operation failed due to insufficient buffer space. The destination buffer contains a truncated, null-terminated version of the intended result. In situations where truncation is acceptable, this may not necessarily be seen as a failure condition. |
Remarks
Behavior is undefined if the strings pointed to by pszDest, pszFormat, or any argument strings overlap.
Neither pszFormat nor pszDest should be NULL. See StringCchPrintf_lEx if you require the handling of null string pointer values.
In order to use this function, you must define the following macro in your header file, before including StrSafe.h.
#define STRSAFE_LOCALE_FUNCTIONS
Note
The strsafe.h header defines StringCchPrintf_l as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
