feof(3) Library Functions Manual feof(3) NAME
feof - Tests EOF on a stream LIBRARY
Standard C Library (libc) SYNOPSIS
#include <stdio.h> int feof( FILE *stream); STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: feof(): XSH5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. PARAMETERS
Specifies the input stream. DESCRIPTION
The feof() function tests the EOF (end-of-file) condition on the specified stream. NOTES
[Tru64 UNIX] The feof() function may be a macro (depending on the compile-time definitions used in the source). Consequently, you cannot use this interface where a function is necessary; for example, a subroutine pointer cannot point to it. RETURN VALUES
If EOF has previously been detected reading the input stream specified by the stream parameter, a nonzero value is returned. Otherwise, a value of 0 (zero) is returned. RELATED INFORMATION
Functions: ferror(3), fileno(3), clearerr(3), fopen(3) Standards: standards(5) delim off feof(3)
