oadHints : LoadHints
This property holds give the load() function some hints on how it should behave.
You can give some hints on how the symbols are resolved. Usually, the symbols are not resolved at load time, but resolved lazily, (that is, when resolve() is called). If you set the loadHint to ResolveAllSymbolsHint, then all symbols will be resolved at load time if the platform supports it.
Setting ExportExternalSymbolsHint will make the external symbols in the library available for resolution in subsequent loaded libraries.
If LoadArchiveMemberHint is set, the file name is composed of two components: A path which is a reference to an archive file followed by the second component which is the reference to the archive member. For instance, the fileName libGL.a(shr_64.o) will refer to the library shr_64.o in the archive file named libGL.a. This is only supported on the AIX platform.
The interpretation of the load hints is platform dependent, and if you use it you are probably making some assumptions on which platform you are compiling for, so use them only if you understand the consequences of them.
By default, none of these flags are set, so libraries will be loaded with lazy symbol resolution, and will not export external symbols for resolution in other dynamically-loaded libraries.

enum QLibrary::LoadHint
flags QLibrary::LoadHints
This enum describes the possible hints that can be used to change the way libraries are handled when they are loaded.
Constant Value Description
QLibrary::ResolveAllSymbolsHint 0x01 Try to resolve all symbols in a library as soon as it is loaded.
QLibrary::ExportExternalSymbolsHint 0x02 Export unresolved symbols in the library so that they can be resolved in other dynamically-loaded libraries.
QLibrary::LoadArchiveMemberHint 0x04 Allow the file name of the library to specify a particular object file within an archive file.
The LoadHints type is a typedef for QFlags<LoadHint>. It stores an OR combination of LoadHint values.
