+.SH NAME
+stdio.h \- standard buffered input/output
+.SH SYNOPSIS
+.LP
+\fB#include <stdio.h>\fP
+.SH DESCRIPTION
+.LP
+Some of the functionality described on this reference page extends
+the ISO\ C standard. Applications shall define
+the appropriate feature test macro (see the System Interfaces volume
+of IEEE\ Std\ 1003.1-2001, Section 2.2, The Compilation Environment)
+to enable the visibility of these symbols in this
+header.
+.LP
+The \fI<stdio.h>\fP header shall define the following macros as positive
+integer constant expressions:
+.TP 7
+BUFSIZ
+Size of \fI<stdio.h>\fP buffers.
+.TP 7
+_IOFBF
+Input/output fully buffered.
+.TP 7
+_IOLBF
+Input/output line buffered.
+.TP 7
+_IONBF
+Input/output unbuffered.
+.TP 7
+L_ctermid
+Maximum size of character array to hold \fIctermid\fP() output.
+.TP 7
+L_tmpnam
+Maximum size of character array to hold \fItmpnam\fP() output.
+.TP 7
+SEEK_CUR
+Seek relative to current position.
+.TP 7
+SEEK_END
+Seek relative to end-of-file.
+.TP 7
+SEEK_SET
+Seek relative to start-of-file.
+.sp
+.LP
+The following macros shall be defined as positive integer constant
+expressions which denote implementation limits:
+.TP 7
+{FILENAME_MAX}
+Maximum size in bytes of the longest filename string that the implementation
+guarantees can be opened.
+.TP 7
+{FOPEN_MAX}
+Number of streams which the implementation guarantees can be open
+simultaneously. The value is at least eight.
+.TP 7
+{TMP_MAX}
+Minimum number of unique filenames generated by \fItmpnam\fP(). Maximum
+number of times
+an application can call \fItmpnam\fP() reliably. The value of {TMP_MAX}
+is at least 25.
+\ On XSI-conformant systems, the value of {TMP_MAX} is at least 10000.
+.sp
+.LP
+The following macro name shall be defined as a negative integer constant
+expression:
+.TP 7
+EOF
+End-of-file return value.
+.sp
+.LP
+The following macro name shall be defined as a null pointer constant:
+.TP 7
+NULL
+Null pointer.
+.sp
+.LP
+The following macro name shall be defined as a string constant:
+.TP 7
+P_tmpdir
+Default directory prefix for \fItempnam\fP().
+.sp
+.LP
+The following shall be defined as expressions of type "pointer to
+\fBFILE\fP" that point to the \fBFILE\fP objects
+associated, respectively, with the standard error, input, and output
+streams:
+.TP 7
+\fIstderr\fP
+Standard error output stream.
+.TP 7
+\fIstdin\fP
+Standard input stream.
+.TP 7
+\fIstdout\fP
+Standard output stream.
+.sp
+.LP
+The following data types shall be defined through \fBtypedef\fP:
+.TP 7
+\fBFILE\fP
+A structure containing information about a file.
+.TP 7
+\fBfpos_t\fP
+A non-array type containing all information needed to specify uniquely
+every position within a file.
+.TP 7
+\fBva_list\fP
+As described in \fI<stdarg.h>\fP .
+.TP 7
+\fBsize_t\fP
+As described in \fI<stddef.h>\fP .
+.sp
+.LP
+The following shall be declared as functions and may also be defined
+as macros. Function prototypes shall be provided.
