Standard C Library Functions                           ferror(3C)



NAME
     ferror, feof, clearerr, fileno - stream status inquiries

SYNOPSIS
     #include 

     int ferror(FILE *stream);


     int feof(FILE *stream);


     void clearerr(FILE *stream);


     int fileno(FILE *stream);


DESCRIPTION
     The ferror() function returns a non-zero value when an error
     has previously occurred reading from or writing to the named
     stream (see Intro(3)). It returns 0 otherwise.


     The feof() function returns a non-zero value  when  EOF  has
     previously  been detected reading the named input stream. It
     returns 0 otherwise.


     The clearerr() function resets the error indicator  and  EOF
     indicator to 0 on the named stream.


     The fileno() function returns the  integer  file  descriptor
     associated with the named stream; see open(2).
