Enumeration Type Documentation

enum VfsMountFlags

Enumerator
VFS_MOUNT_WATCH	all real directories mounted during this operation will be watched for changes. this flag is provided to avoid watches in output-only directories, e.g. screenshots/ (only causes unnecessary overhead).
VFS_MOUNT_ARCHIVABLE	anything mounted from here should be included when building archives.
VFS_MOUNT_MUST_EXIST	return ERR::VFS_DIR_NOT_FOUND if the given real path doesn't exist. (the default behavior is to create all real directories in the path)
VFS_MOUNT_KEEP_DELETED	keep the files named "*.DELETED" visible in the VFS directories. the standard behavior of hiding the file with the same name minus the ".DELETED" suffix will still apply. (the default behavior is to hide both the suffixed and unsuffixed files)
VFS_MOUNT_REPLACEABLE	mark a directory replaceable, so that when writing a file to this path new real directories will be created instead of reusing already existing ones mounted at a subpath of the VFS path. (the default behaviour is to write to the real directory associated with the VFS directory that was last mounted to this path (or subpath))

Function Documentation

LIB_API PIVFS CreateVfs

(

size_t

cacheSize

)

create an instance of a Virtual File System.

Parameters

cacheSize

size [bytes] of memory to reserve for a file cache, or zero to disable it. if small enough to fit, file contents are stored here until no references remain and they are evicted.

note: there is no limitation to a single instance, it may make sense to create and destroy VFS instances during each unit test.
