[−][src]Struct qt_core::q_file_device::MemoryMapFlags
This enum describes special options that may be used by the map() function.
C++ enum: QFileDevice::MemoryMapFlags
.
This enum describes special options that may be used by the map() function.
This enum was introduced or modified in Qt 4.4.
Methods
impl MemoryMapFlags
[src]
impl MemoryMapFlags
[src]
pub const NoOptions: MemoryMapFlags
[src]
No options. (C++ enum variant: NoOptions = 0
)
pub const MapPrivateOption: MemoryMapFlags
[src]
The mapped memory will be private, so any modifications will not be visible to other processes and will not be written to disk. Any such modifications will be lost when the memory is unmapped. It is unspecified whether modifications made to the file made after the mapping is created will be visible through the mapped memory. This enum value was introduced in Qt 5.4. (C++ enum variant: MapPrivateOption = 1
)
