determine if the current position of a file is at the end

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

feof(file)

Parameters

file

-

file name or file descriptor

Description

• 

feof returns true if and only if the end of a STREAM file has been reached during a readline, readbytes, or fscanf operation. Otherwise, feof returns false.

• 

The end of file must actually have been encountered. For example, asking readbytes to read 20 bytes when only 19 remain in the file will result in a subsequent feof call returning true. On the other hand, reading the last line of a file with readline does not encounter the end of file; a subsequent call to readline will.

• 

if a file name is given, and that file is not yet open, it is opened in READ mode with type BINARY.
