+.TH EOF 3const 2023-02-05 "Linux man-pages 6.05.01"
+.SH NAME
+EOF \- end of file or error indicator
+.SH LIBRARY
+Standard C library
+.RI ( libc )
+.SH SYNOPSIS
+.nf
+.B #include <stdio.h>
+.PP
+.BR "#define EOF " "/* ... */"
+.fi
+.SH DESCRIPTION
+.B EOF
+represents the end of an input file, or an error indication.
+It is a negative value, of type
+.IR int .
+.PP
+.B EOF
+is not a character
+(it can't be represented by
+.IR "unsigned char" ).
+It is instead a sentinel value outside of the valid range for valid characters.
+.SH CONFORMING TO
+C99 and later;
+POSIX.1-2001 and later.
+.SH CAVEATS
+Programs can't pass this value to an output function
+to "write" the end of a file.
+That would likely result in undefined behavior.
+Instead,
+closing the writing stream or file descriptor
+that refers to such file
+is the way to signal the end of that file.

+.TH NULL 3const 2023-02-05 "Linux man-pages 6.05.01"
+.SH NAME
+NULL \- null pointer constant
+.SH LIBRARY
+Standard C library
+.RI ( libc )
+.SH SYNOPSIS
+.nf
+.B #include <stddef.h>
+.PP
+.B "#define NULL ((void *) 0)"
+.fi
+.SH DESCRIPTION
+.B NULL
+represents a null pointer constant,
+that is, a pointer that does not point to anything.
+.SH CONFORMING TO
+C99 and later;
+POSIX.1-2001 and later.
+.SH NOTES
+The following headers also provide
+.BR NULL :
+.IR <locale.h> ,
+.IR <stdio.h> ,
+.IR <stdlib.h> ,
+.IR <string.h> ,
+.IR <time.h> ,
+.IR <unistd.h> ,
+and
+.IR <wchar.h> .
+.SH CAVEATS
+It is undefined behavior to dereference a null pointer,
+and that usually causes a segmentation fault in practice.
+.PP
+It is also undefined behavior to perform pointer arithmetic on it.
+.PP
+.I NULL \- NULL
+is undefined behavior, according to ISO C, but is defined to be 0 in C++.
+.PP
+To avoid confusing human readers of the code,
+do not compare pointer variables to
+.BR 0 ,
+and do not assign
+.B 0
+to them.
+Instead, always use
+.BR NULL .
+.PP
+.B NULL
+shouldn't be confused with
+.BR NUL ,
+which is an
+.BR ascii (7)
+character,
+represented in C as
+.BR \[aq]\e0\[aq] .
+.SH BUGS
+When it is necessary to set a pointer variable to a null pointer,
+it is not enough to use
+.BR memset (3)
+to zero the pointer
+(this is usually done when zeroing a struct that contains pointers),
+since ISO C and POSIX don't guarantee that a bit pattern of all 0s
+represent a null pointer.
+See the EXAMPLES section in
+.BR getaddrinfo (3)
+for an example program that does this correctly.
