This function is not available in Windows.
Assume there is a file “Read me.txt” with the text “Hello!” in it. Then:
Set Field [ MyTextField ; TrFile_GetResForkSize ( "-Unused" ; "Disk:Read me.txt" ) ]
might return 453 which is the size of the resource fork.
We assume that in your FileMaker file the following fields are defined:
gFileSpec Global, text gSize Global, number
gFileSpec should contain the path to an existing file, for example “Mac HD:Readme.txt”. In a script add the following scriptstep:
Set Field [ gSize ; TrFile_GetResForkSize ( "-Unused" ; gFileSpec ) ]
This will fill gSize with the resource fork size of the file.
