Re: Max string size of filePath+filenName

[David Gillies <daggillies@xxxxxxxxx>]

Much better: pathconf(3). Use _PC_PATH_MAX and
_PC_NAME_MAX:

#include <unistd.h>
int GetMaxPath(void)
   {
   int						len;
   
   len=pathconf("/",_PC_PATH_MAX);
   return len;
   }

int GetMaxName(void)
{
   int						len;
   
	len=pathconf("/",_PC_NAME_MAX);
	return len;
}
