pe_projcs_unload_constants

Unloads the constants for a projected coordinate system object.

Usage syntax

void pe_projcs_unload_constants (PE_PROJCS projcs);

Parameters

Description

Many projections calculate intermediate values that are constants for a particular set of parameters and spheroid. You use pe_projcs_load_constants to load the values into memory. The pe_projcs_unload_constants function will remove these values from memory if they are loaded. You can also delete the projected coordinate system to remove the constants from memory. You can check whether the constants are loaded with pe_projcs_isconstloaded.

Returns

None

Examples

pe_projcs_unload_constants(spcs_ca5);
