Hi guys,
In OSX, StandardFileStream byteID size is 20, while in Linux, it is 16. I
see this definition in ./Cross/plugins/FilePlugin/FilePlugin.h
/* squeak file record; see sqFilePrims.c for details */
typedef struct {
int sessionID; /* ikp: must be first */
void *file;
squeakFileOffsetType fileSize; /* 64-bits we hope. */
#if defined(ACORN)
// ACORN has to have 'lastOp' as at least a 32 bit field in order to work
int lastOp; // actually used to save file position
char writable;
char lastChar;
char isStdioStream;
#else
char writable;
char lastOp; /* 0 = uncommitted, 1 = read, 2 = write */
char lastChar;
char isStdioStream;
#endif
} SQFile;
And I see no override from UNIX platform code. So...how can that be 16
bytes in Linux?
Thanks in advance,
