NAME

       clearerr - Clears indicators on a stream

LIBRARY

SYNOPSIS

       #include <stdio.h>

       void clearerr(
	   FILE *stream);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       clearerr(): XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies the input or output stream to be cleared.

DESCRIPTION

       The clearerr() function resets the error indicator and the EOF indicator for the stream specified by the stream parameter.

NOTES

       [Tru64 UNIX]  The clearerr() function is supported for multithreaded applications.

RETURN VALUES

       The clearerr() function returns no value.

NAME

       ferror - Tests the error indicator on a stream

LIBRARY

       Standard C Library (libc)

SYNOPSIS

       #include <stdio.h>

       int ferror(
	       FILE *stream);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       ferror(): XSH5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies the input or output stream.

DESCRIPTION

       The ferror() function tests whether input/output errors have occurred on the specified stream.

NOTES

       [Tru64  UNIX]  The ferror() function may be a macro (depending on the compile-time definitions used in the source).  Consequently, you can-
       not use this interface where a function is necessary; for example, a subroutine pointer cannot point to it.

RETURN VALUES

       If an I/O error occurred when reading from or writing to the stream specified by the stream parameter, a nonzero value is returned.  Other-
       wise, a value of 0 (zero) is returned.
