[rrd-developers] rrd_tool.h windows suggestions

[Gifford Hesketh]

instead of:

/* Win32 only includes */

#include <float.h>        /* for _isnan  */
#define isnan _isnan
#define finite _finite
#define isinf(a) (_fpclass(a) == _FPCLASS_NINF || _fpclass(a) == _FPCLASS_PINF)
struct tm* localtime_r(const time_t *timep, struct tm* result);
char* ctime_r(const time_t *timep, char* result);
struct tm* gmtime_r(const time_t *timep, struct tm* result);
char *strtok_r(char *str, const char *sep, char **last);


I use (threadsafe stuff from pthreads):

#include <float.h>        /* for _isnan  */
#ifndef isnan 
	#define isnan _isnan
#endif
#ifndef finite
	#define finite _finite
#endif
#ifndef isinf 
	#define isinf(a) (_fpclass(a) == _FPCLASS_NINF || _fpclass(a) == _FPCLASS_PINF)
#endif

#if !defined(__MINGW32__)
#define strtok_r( _s, _sep, _lasts ) \
        ( *(_lasts) = strtok( (_s), (_sep) ) )
#endif /* !__MINGW32__ */

#define asctime_r( _tm, _buf ) \
        ( strcpy( (_buf), asctime( (_tm) ) ), \
          (_buf) )

#define ctime_r( _clock, _buf ) \
        ( strcpy( (_buf), ctime( (_clock) ) ),  \
          (_buf) )

#define gmtime_r( _clock, _result ) \
        ( *(_result) = *gmtime( (_clock) ), \
          (_result) )

#define localtime_r( _clock, _result ) \
        ( *(_result) = *localtime( (_clock) ), \
          (_result) )

#define rand_r( _seed ) \
        ( _seed == _seed ? rand() : rand() )
