Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The fscanf 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 with a type
     corresponding to a type specifier in <format>.
 
     The <format> argument controls the interpretation of the input
     fields and has the same form and function as the <format>
     argument for the scanf function. See scanf for a description of
     the <format> argument.
 
     Return Value
 
     The fscanf function returns the number of fields that were
     successfully converted and assigned. The return value does not
     include fields that were read but not assigned.
 
     The return value is EOF for an attempt to read at end-of-file. A
     return value of 0 means that no fields were assigned.
