[Description]
Checks whether a character is a graph character.

[Explanation]
isgraph returns nonzero if <I>c</I> is printing character, like
<A HREF="$$LINK(ctype.h/isprint)">isprint</A>, except that a space character is excluded; otherwise it returns zero.
It is an inline function which is implemented using GNU C smart macros, which expands to a
relatively small code.
