Arguments

 

file_ptr

   A pointer to the file that provides input text.
 

format_spec

   A pointer to a character string that contains the format
   specification.
 

 . . .

   Optional expressions whose results correspond to conversion
   specifications given in the format specification.

   If no conversion specifications are given, you can omit the input
   pointers. Otherwise, the function calls must have exactly as
   many input pointers as there are conversion specifications, and
   the conversion specifications must match the types of the input
   pointers.

   Conversion specifications are matched to input sources in left-
   to-right order. Excess input pointers, if any, are ignored.
