inlinestaticnoexcept |
Opens the given native library, assuming it has the same base name on all platforms.
The searchSystemPath
argument changes the behavior to either use the default system path or not at all.
Assuming searchSystemPath
is true
, the searchSystemPathFirst
argument changes the behavior to first search the default system path rather than searching it last.
libName | library name, with or without prefix and suffix |
searchSystemPath | if true library shall be searched in the system path (default), otherwise false . |
searchSystemPathFirst | if true system path shall be searched first (default), rather than searching it last. if searchSystemPath is false this argument is ignored. |
global | if true allows system wide access of the loaded library, otherwise access is restricted to the process. |
NativeLibrary
instance, use isValid() to check whether the native library was loaded successful. Definition at line 152 of file native_lib.hpp.
