LSCanURLAcceptURL(_:_:_:_:_:)

Tests whether an app can accept (open) an item for a URL.

Declaration

func LSCanURLAcceptURL(_ inItemURL: CFURL, _ inTargetURL: CFURL, _ inRoleMask: LSRolesMask, _ inFlags: LSAcceptanceFlags, _ outAcceptsItem: UnsafeMutablePointer<DarwinBoolean>) -> OSStatus

Parameters

inItemURL:
A Core Foundation URL reference designating the source item (the item to test for acceptance by the target application); see the CFURL Reference in the Core Foundation Reference Documentation for a description of the CFURLRef data type.
inTargetURL:
A Core Foundation URL reference designating the target application; see the CFURL Reference in the Core Foundation Reference Documentation for a description of the CFURLRef data type. The URL must have scheme file and contain a valid path to an application file or application bundle.
inRolesMask:
A bit mask specifying the target app’s desired role or roles with respect to the source item; see Lsrolesmask for a description of this mask. This parameter applies only to URLs with a scheme component of file, and is ignored for all other schemes. If the role is unimportant, pass kLSRolesAll.
inFlags:
Flags specifying behavior to observe during the acceptance test; see Lsacceptanceflags for a description of these flags.
outAcceptsItem:
A pointer to a Boolean value that, on return, will indicate whether the target application can accept the source item with at least one of the specified roles.

Return Value

A result code; see Result Codes.

Discussion

If the item URL’s scheme is file (designating either a file or a directory), the acceptance test is based on the designated item’s filename extension, file type, and creator signature, along with the role specified by the inRolesMask parameter; otherwise, it is based on the URL scheme (such as http, ftp, or mailto).
