[Python-checkins] python/dist/src/Modules datetimemodule.c,NONE,1.1

2002年12月16日 12:18:16 -0800

Update of /cvsroot/python/python/dist/src/Modules
In directory sc8-pr-cvs1:/tmp/cvs-serv26267/python/Modules
Added Files:
	datetimemodule.c 
Log Message:
datetime escapes the sandbox. The Windows build is all set. I leave it
to others to argue about how to build it on other platforms (on Windows
it's in its own DLL).
--- NEW FILE: datetimemodule.c ---

/* We require that C int be at least 32 bits, and use int virtually
 * everywhere. In just a few cases we use a temp long, where a Python
 * API returns a C long. In such cases, we have to ensure that the
 * final result fits in a C int (this can be an issue on 64-bit boxes).
