Storage location for data.
The size of the buffer in single-byte or wide characters, which is also the maximum number of characters to be read.
The number of characters actually read.
The return value is zero if successful; otherwise, an error code if a failure occurs.
_cgetws_s read a string from the console and copy the string (with a null terminator) into
_cgetws_s is the wide character version of the function; other than the character size, the behavior of these two functions is identical. The maximum size of the string to be read is passed in as the
numberOfElements parameter. This size should include an extra character for the terminating null. The actual number of characters read is placed in
If an error occurs during the operation or in the validating of the parameters, the invalid parameter handler is invoked, as described in Parameter Validation . If execution is allowed to continue,
errno is set to
EINVAL is returned.
In C++, the use of these functions is simplified by template overloads; the overloads can infer buffer length automatically, thereby eliminating the need to specify a size argument, and they can automatically replace older, less-secure functions with their newer, more secure counterparts.
