+.Sh NAME
+.Nm isgraph
+.Nd printing character test (space character exclusive)
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In ctype.h
+.Ft int
+.Fn isgraph "int c"
+.Sh DESCRIPTION
+The
+.Fn isgraph
+function tests for any printing character except space
+.Pq Ql "\~"
+and other
+locale-specific space-like characters.
+The value of the argument must be representable as an
+.Vt "unsigned char"
+or the value of
+.Dv EOF .
+.Pp
+In the ASCII character set, this includes the following characters
+(with their numeric values shown in octal):

+.Sh RETURN VALUES
+The
+.Fn isgraph
+function returns zero if the character tests false and
+returns non-zero if the character tests true.
+.Sh COMPATIBILITY
+The
+.Bx 4.4
+extension of accepting arguments outside of the range of the
+.Vt "unsigned char"
+type in locales with large character sets is considered obsolete
+and may not be supported in future releases.
+The
+.Fn iswgraph
+function should be used instead.
+.Sh SEE ALSO
+.Xr ctype 3 ,
+.Xr iswgraph 3 ,
+.Xr ascii 7
+.Sh STANDARDS
+The
+.Fn isgraph
+function conforms to
+.St -isoC .
