Typedef Documentation

Structure of the circular Geographical Area, specified with a center coordinates and a radius.

This structure represents a circular Geographical Area.

Since :
2.4
Remarks:
Do not use maps_area_circle_s directly if you are an application developer.
typedef void* maps_area_h

Handle of the Geographical Area.

The Geographical Area handle can be obtained via call of maps_area_create_rectangle() or maps_area_create_circle().
To release the handle use maps_area_destroy().
To clone the handle use maps_area_clone().

Since :
2.4
See also:
maps_area_create_rectangle()

Structure of the rectangular Geographical Area.

This structure represents a rectangular Geographical Area, specified with left top and right bottom coordinates.

Since :
2.4
Remarks:
Do not use maps_area_rectangle_s directly if you are an application developer.
typedef struct _maps_area_s maps_area_s

Structure of the Geographical Area.

This structure represents a Geographical Area, specified with a type, circular or rectangular, and appropriate coordinates and radius.

Since :
2.4
Remarks:
Do not use maps_area_s directly if you are an application developer. Using maps_area_h is recommended.

Enumeration Type Documentation

Enumeration for supported types of the Geographical Area.

Function Documentation

int maps_area_clone ( const maps_area_h  origin,
maps_area_h cloned 
)

Clones the Geographical Area.

This function makes a clone of the origin Geographical Area of type maps_area_h.

Since :
2.4
Remarks:
cloned must be released using maps_area_destroy().
Parameters:
[in]originThe area maps_area_h to be copied
[out]clonedThe cloned area maps_area_h handle
Returns:
0 on success, otherwise a negative error value
Return values:
MAPS_ERROR_NONESuccessful

int maps_area_create_circle ( const maps_coordinates_h  center,
const double  radius,
maps_area_h area 
)

Creates a circular type of new Geographical Area with a specified information.

This function creates a circular type of new maps_area_h Geographical Area with a specified center coordinates and a radius.

Since :
2.4
Remarks:
area must be released using maps_area_destroy().
center must be released using maps_coordinates_destroy().
The radius is specified in units, listed in maps_distance_unit_e.
To get and set distance units use maps_preference_get_distance_unit() and maps_preference_set_distance_unit() respectively.
Parameters:
[in]centerThe central position of the area
[in]radiusThe radius of the area
[out]areaThe area handle
Returns:
0 on success, otherwise a negative error value
Return values:
