Description
|
|
eptASCII
|
Specifies that the parameter is a null-terminated character string.
|
|
eptByte
|
Specifies that the parameter is an 8-bit unsigned integer.
|
|
eptLong
|
Specifies that the parameter is a 32-bit unsigned integer.
|
|
eptLongRange
|
Specifies that the parameter is an array of two, 32-bit unsigned integers. The pair of integers represents a range of numbers. The first integer is the smallest number in the range, and the second integer is the largest number in the range.
|
|
eptNone
|
Represents constant eptNone.
|
|
eptRational
|
Specifies that the parameter is an array of two, 32-bit unsigned integers. The pair of integers represents a fraction. The first integer in the pair is the numerator, and the second integer in the pair is the denominator.
|
|
eptRationalRange
|
Specifies that the parameter is an array of four, 32-bit unsigned integers. The first two integers represent one fraction, and the second two integers represent a second fraction. The two fractions represent a range of rational numbers. The first fraction is the smallest rational number in the range, and the second fraction is the largest rational number in the range.
|
|
eptShort
|
Specifies that the parameter is a 16-bit unsigned integer.
|
|
eptUndefined
|
Specifies that the parameter is an array of bytes that can hold values of any type.
