This call allows file transfers within the desktop for the specified file type to be intercepted. The same pollword as returned by PsiFS_Register must be specified. The types of intercept to claim are specified by setting bits in the mask passed in R2:
If no bits are set in the mask then the intercept is released. Alternatively, all intercepts may be released by calling PsiFS_InterceptRelease or PsiFS_Unregister. The user may force a file transfer intercept by pressing Left Alt or disable an intercept by pressing Right Alt. PsiFS_InterceptPoll should be used to check for new intercepted file transfers when the poll word is non-zero. | ||||||||||||||||||
