|
The function <function>fscanf</function> is similar to
|
|
<function>sscanf</function>, but it takes its input from a file
|
|
associated with <parameter>handle</parameter> and interprets the
|
|
input according to the specified
|
|
<parameter>format</parameter>. If only two parameters were passed
|
|
to this function, the values parsed will be returned as an array.
|
|
Otherwise, if optional parameters are passed, the function will
|
|
return the number of assigned values. The optional parameters
|
|
must be passed by reference.
