ARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
eu_conv = the polynomial set to be obtained. Value must be an integer equal to 9 (User0) or 10 (User1).
fwdcoeff[] = a return array of forward conversion polynomial coefficients. Coefficients c
0
through c
12
are
represented in array elements [0] through [12], respectively. Valid return values: -3e+38 to 3e+38.
invcoeff[] = a return array of inverse conversion polynomial coefficients. Coefficients d
0
through d
12
are represented
in array elements [0] through [12], respectively. Valid return values: -3e+38 to 3e+38.

ESCRIPTION
This function returns the user-defined conversion polynomials. All twelve elements of the arrays are returned,
regardless of how many were set with the vtex10xxA_set_user_conversion function.
The valid return values for the
eu_conv parameter are:
