Microsoft's stdlib.h defines the following: #ifndef _MAC #define _MAX_PATH 260 /* max. length of full pathname */ #define _MAX_DRIVE 3 /* max. length of drive component */ #define _MAX_DIR 256 /* max. length of path component */ #define _MAX_FNAME 256 /* max. length of file name component */ #define _MAX_EXT 256 /* max. length of extension component */
In windef.h, they also define MAX_PATH to be 260. (This is include files that came with VC++ 6.0).
