* <FUNCTION DESCRIPTION>
|
|
* The fwscanf_s function is the wide-character equivalent of the
|
|
* fscanf_s function The fwscanf_s function reads data from the current position
|
|
* of stream into the locations given by argument (if any). Each argument must
|
|
* be a pointer to a variable of a type that corresponds to a type specifier in
|
|
* format. format controls the interpretation of the input fields and has the
|
|
* same form and function as the format argument for scanf.
|
|
*
|
|
* <INPUT PARAMETERS>
|
|
* stream Pointer to FILE structure.
|
|
* format Format control string, see Format Specifications.
|
|
* ... Optional arguments.
|
|
*
|
|
* <OUTPUT PARAMETERS>
|
|
* ... The converted value stored in user assigned
|
|
* address
|
|
*
|
|
* <RETURN VALUE>
|
|
* Each of these functions returns the number of fields successfully
|
|
* converted and assigned; the return value does not include fields that were
|
|
* read but not assigned. A return value of 0 indicates that no fields were
|
|
* assigned. return -1 if an error occurs.
