Method Detail

loadNativeLibrary

public static boolean loadNativeLibrary(String directoryPath,
                        String loadedLibName,
                        com.serialpundit.core.SerialComSystemProperty serialComSystemProperty,
                        int osType,
                        int cpuArch,
                        int abitype)
                                 throws com.serialpundit.core.SerialComException

Extract native library from jar in a 'directoryPath' directory, load and link it. Native library is found in the root of 'sp-ioctl.jar' file.

Parameters:

directoryPath - null for default directory or user supplied directory path.

loadedLibName - null for default name or user supplied name of loaded library.

serialComSystemProperty - instance of SerialComSystemProperty to get required java properties.

cpuArch - architecture of CPU this library is running on.

osType - operating system this library is running on.

abitype - binary application interface type to correctly link.

Throws:

com.serialpundit.core.SerialComException - if java system properties can not be is null, if any file system related issue occurs.

SecurityException - if java system properties can not be accessed or required files can not be accessed.

UnsatisfiedLinkError - if loading/linking shared library fails.
