|
||
|
|
* the formatting a bit.
|
||
|
|
* 04-10-90 GJF Now _CALLTYPE1.
|
||
|
|
* 06-05-90 SBM Recoded as pure 32-bit, using new file handle state bits
|
||
|
|
* 07-24-90 SBM Removed '32' from API names
|
||
|
|
* 09-28-90 GJF New-style function declarator.

|
|
* 12-08-95 SKS _confh is now initialized on demand
|
