  ANNANGLE_RADIANS The angle is measured in radians. The default abbreviation for this unit is "rad".
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.
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.

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.
