There are a number of macros in cutil.h and some of the multiline ones are defined in a way that can produce syntax errors when used in a if … else … block. For instance there is
# define CUFFT_SAFE_CALL( call) { \
cufftResult err = call; \
if( CUFFT_SUCCESS != err) { \
fprintf( stderr, "CUFFT error in file '%s' in line %i.\n", \
__FILE__, __LINE__); \
exit(EXIT_FAILURE); \
} }
and if it is used as
if( something )
CUFFT_SAVE_CALL( call );
else
something else
will give a syntax error. The usual way to define multistatement macros is to wrap it in a do{ … }while(0) block which doesn’t have the above problem.
