Can someone help me with Macintosh file manipulation from C? Two things in particular bother me. The one is the second variable in the i/o functions listed in libos.c ; what purpose does it serve? The other is that lint refuses to accept the type ioPParam, but is perfectly happy with ioParam (The type in osintf.h is ioPParam). Why? I would greatly appreciate any suggestions. Steve Engel Please try to check your Inside Macintosh first before sending a question to info-mac. If you are receiving the Inside Mac updates, you should have a new File Manager document dated 5/21/84. Look at the section titled "High Level File Manager Routines"; a sample of these calls can be found in the cmd/fromhex.p program in the distribution, or in Mike Schuster's translation, fromhex.c. The calls you are refering to are discussed in "Low Level File Manager Routines" and are normally not used. The second parameter on these calls is a boolean (0 or 1) to indicate whether the function is asynchronous or synchronous. The osintf.h on the distribution looks OK to me; the structure defined there is "ioParam".
