5.47.3 Darwin Pragmas
The following pragmas are available for all architectures running the
Darwin operating system. These are useful for compatibility with other
Mac OS compilers.
mark tokens...- This pragma is accepted, but has no effect.
options align=alignment- This pragma sets the alignment of fields in structures. The values of
alignment may be
mac68k, to emulate m68k alignment, or
power, to emulate PowerPC alignment. Uses of this pragma nest
properly; to restore the previous setting, use reset for the
alignment.
segment tokens...- This pragma is accepted, but has no effect.
unused (var [, var]...)- This pragma declares variables to be possibly unused. GCC will not
produce warnings for the listed variables. The effect is similar to
that of the
unused attribute, except that this pragma may appear
anywhere within the variables' scopes.
