Set the player.

Set window position according to menu's on-top setting:

Set up the tables required for fast square root computation.

Shutdown after a critical error.

Spawn a brush.

UStruct inline comparer.

Remove an object from the hash table.

Unhold the viewport, and perform any latent resizing.

Update a bounding volume by expanding it to enclose a list of polys.

Update a convolution hull with a list of polys.

Update user viewport interface.

Return a uniformly distributed random unit vector.

Calculate the size of a string built from a font, word wrapped to a specified region.

Close the log file.

Shut down the platform-specific subsystem. Not guarded.

Gets the extension of a file, such as "PCX". Returns NULL if none. string if there's no extension.

Launch a uniform resource locator (i.e. http://www.epicgames.com/unreal). This is expected to return immediately as the URL is launched by another tas

Swap memory in one buffer with another

Move a file and overwrite the destination.

Build bounding volumes for all Bsp nodes. The bounding volume of the node completely encloses the "outside" space occupied by the nodes. Note that t

Temporary!!

Update a the master brush EdPoly corresponding to a newly-changed poly to reflect its new properties. Doesn't do any transaction tracking. Assumes y

Transformations in optimized assembler format. An adaption of Michael Abrash' optimal transformation code.

Make a time-sorted list of all actors which overlap a cylinder moving along a line from Start to End. If LevelInfo is specified, also checks for colli

Make a list of all actors which overlap with a cylinder at Location with the given collision size.

Add all of a node's vertices to a node-vertex list.

Add a unique option to the URL, replacing any existing one.

Add a point to a Bsp node before a specified vertex (between it and the previous one). VertexNumber can be from 0 (before first) to Node->NumVertices

Add a new allocation to the list of tracked allocations.

Allocate subobjects for a model.

Allocate an array of INDEX's for the elements in a database object from Num to Max. These elements of level objects are reserved for use by moving br

Allocate a linear span buffer and initialize it to represent the yet-undrawn region of a viewport.

Create a new object or replace an existing one. If Name is NAME_None, tries to create an object with an arbitrary unique name. No failure conditions.

Make sure that a span buffer is valid. Performs the following checks: - Make sure there are no zero-length spans - Make sure there are no negative-le
