Return information about the opened sample file. New programs are recommended to use PlayIt_FileInfo
instead.
R0 to R4 are exactly the information returned from PlayIt_Open
. This SWI enables files opened with the command line interface to still be identified by other software. In addition R5 returns how many sample frames there are in the file (and hence, in combination with the frame rate, how many seconds long it is). This defines the limits imposed on the parameters of PlayIt_BeginEnd
and PlayIt_SetPtr
. The length of the sample file in seconds is simply R5/R2.
An error is returned if no file is open.
