Get the type of the next token to read.

Type code for the next token or a negative value in case of a read error (end of stream). Possible values are:

BINDRV_TYP_INT	An integer
BINDRV_TYP_REAL	A real (as a double)
BINDRV_TYP_STR	A text string
BINDRV_TYP_BOOL	A Boolean
BINDRV_TYP_CTRL	A control token
BINDRV_TYP_LONG	A long integer (64bit)

This routine does not return the token itself but indicates which function to use for reading it. For instance, if the return value is BINDRV_TYP_INT, the function bindrv_getint has to be called to retrieve an integer value.

bindrv_getint, bindrv_getreal, bindrv_getstring, bindrv_getbool, bindrv_getctrl, bindrv_getlong.
