C Preprocessor Macro for syslog/fprintf

[bandeg]

Hello:
How can I write a C preprocessor macro that is mapped to syslog versus fprintf depending on the OS.

For instance,

On Linux map to this.
syslog(LOG_xyx, "STUFF %s %d %x", str, avar, bvar);

On Windows map to this. :
fprintf(file, "STUFF %s %d %x", str, avar, bvar);

Thanks,
--B

#ifdef LINUX
#define macro(x,y,z,a,b) syslog(x, y, z, a, b);
#else
#define macro(x,y,z,a,b) fprintf(x, y, z, a, b);
#endif


Check this and do keep us posted.

For reference, you can look into "The Complete C Reference- H.Schildt"

Hi:

I am worried about the variable arguments list. I don't want to have a different macro for every different combination of args to the syslog / printf.

Any other suggestions.

Thanks,

C99 supports variable length macros also! Check the GCC manual and do keep us posted.
