+.Sh NAME

+.Nm getc ,
+.Nm getc_unlocked ,
+.Nm getchar ,
+.Nm getchar_unlocked ,
+.Nm getw
+.Nd get next character or word from input stream
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In stdio.h
+.Ft int
+.Fn fgetc "FILE *stream"
+.Ft int
+.Fn getc "FILE *stream"
+.Ft int
+.Fn getc_unlocked "FILE *stream"
+.Ft int
+.Fn getchar void
+.Ft int
+.Fn getchar_unlocked "void"
+.Ft int
+.Fn getw "FILE *stream"
+.Sh DESCRIPTION
+The
+.Fn fgetc
+function
+obtains the next input character (if present) from the stream pointed at by
+.Fa stream ,
+or the next character pushed back on the stream via
+.Xr ungetc 3 .
+.Pp
+The
+.Fn getc
+function
+acts essentially identically to
+.Fn fgetc ,
+but is a macro that expands in-line.
+.Pp
+The
+.Fn getchar
+function
+is equivalent to
+.Fn getc stdin .
+.Pp
+The
+.Fn getw
+function
+obtains the next
+.Vt int
+(if present)
+from the stream pointed at by
+.Fa stream .
+.Pp
+The
+.Fn getc_unlocked
+and
+.Fn getchar_unlocked
+functions are equivalent to
+.Fn getc
+and
+.Fn getchar
+respectively,
+except that the caller is responsible for locking the stream
+with
+.Xr flockfile 3
+before calling them.
+These functions may be used to avoid the overhead of locking the stream
+for each character, and to avoid input being dispersed among multiple
+threads reading from the same stream.
+.Sh RETURN VALUES
+If successful, these routines return the next requested object
+from the
+.Fa stream .
+Character values are returned as an
+.Vt "unsigned char"
+converted to an
+.Vt int .
+If the stream is at end-of-file or a read error occurs,
+the routines return
+.Dv EOF .
+The routines
+.Xr feof 3
+and
+.Xr ferror 3
+must be used to distinguish between end-of-file and error.
+If an error occurs, the global variable
+.Va errno
+is set to indicate the error.
+The end-of-file condition is remembered, even on a terminal, and all
+subsequent attempts to read will return
+.Dv EOF
+until the condition is cleared with
+.Xr clearerr 3 .
+.Sh SEE ALSO
+.Xr ferror 3 ,
+.Xr flockfile 3 ,
+.Xr fopen 3 ,
+.Xr fread 3 ,
+.Xr getwc 3 ,
+.Xr putc 3 ,
+.Xr ungetc 3
+.Sh STANDARDS
+The
+.Fn fgetc ,
+.Fn getc
+and
+.Fn getchar
+functions
+conform to
+.St -isoC .
+The
+.Fn getc_unlocked
+and
+.Fn getchar_unlocked
+functions conform to
+.St -p1003.1-2001 .
+.Sh BUGS
+Since
+.Dv EOF
+is a valid integer value,
+.Xr feof 3
+and
+.Xr ferror 3
+must be used to check for failure after calling
+.Fn getw .
+The size and byte order of an
+.Vt int
+varies from one machine to another, and
+.Fn getw
+is not recommended for portable applications.
