SeaI/O User Manual
Non Object-Oriented SeaMAX API
The methods following methods have been created to ease use for those more
familiar with non-Object-Oriented or functional design. These functions use the
same parameters as their method counterparts and are used interchangeably.
Before using the functions below, SeaMaxW32Create() should first be called in
order to create a global SeaMAX object and return a pointer as a long data type.
Before the end of program execution, SeaMaxW32Destroy() should be called in
order to clean up the global memory space and release the SeaMAX object.
SeaMaxW32Create
SeaMaxW32Create( void )
Description
Creates an instance of the SeaMAX object in the global memory
space.
Parameters
None
Return Codes
> 0 Success – A long pointer to the SeaMAX
object.
SeaMaxW32Destroy
SeaMaxW32Destroy(CSeaMaxW32* SeaMaxPointer)
Description
Releases the globally allocated SeaMAX object.
Parameters
CSeaMaxW32* SeaMaxPointer
Return Codes
0 Success
