Parameter |
Description |
|
|
pbAcute |
Address of the variable to be updated with a value that indicates whether the inside angle or the outside angle of the protractor is being drawn. Possible values are: |
|
|
|
Value |
Meaning |
|
|
TRUE |
The inside (acute) angle of the protractor is being drawn. |
|
|
FALSE |
The outside (obtuse) angle of the protractor is being drawn. |
|
|
Pass NULL if you do not wish to retrieve this information. |
|
|
puUnit |
Address of the variable to be updated with a value that indicates whether the units of the angle are degrees or radians. Pass NULL if you do not wish to retrieve this information. |
|
|
|
Value |
Meaning |
|
|
ANNANGLE_DEGREES |
The angle is measured in degrees. The default abbreviation for this unit is the degree sign. |
|
|
ANNANGLE_RADIANS |
The angle is measured in radians. The default abbreviation for this unit is "rad". |
|
puAbbrevLen |
Address of the variable to be updated with the length of the abbreviation string that follows the angle. Pass NULL if you do not wish to retrieve this information. |
|
|
pszAbbrev |
Address of the character string to be updated with the abbreviation string that follows the angle. Pass NULL if you do not wish to retrieve this information. |
|
|
puPrecision |
Addresss of the variable to be updated with the number of digits after the decimal. (".") Valid values are 0 200. |
|
|
pdArcRadius |
Address of the variable to be updated with the length of the arc radius. |
|
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
You may wish to call this function once, with pszAbbrev set to NULL, and a pointer for puAbbrevLen. The variable pointed to by puAbbrevLen will contain the length of the abbreviation string. Allocate a buffer of this size and call this function again, passing the newly allocated buffer for pszAbbrev.
