Function (B2R2)

Function Type

Namespace: B2R2.MiddleEnd.ControlFlowAnalysis
Assembly: B2R2.MiddleEnd.ControlFlowAnalysis.dll
Base Type: obj
All Interfaces: ILinkage

Represents a function in a binary, which is essentially a continuous chunk of code. Functions may overlap with each other in rare cases. Function overlapping is rare because we will create a new function when there is an incoming edge in the middle of a funcion,

Constructors

Instance members

Instance member	Description
`this.CFG` Full Usage: `this.CFG` Returns: `LowUIRCFG`	Function's control flow graph. Returns: `LowUIRCFG`
`this.Callees` Full Usage: `this.Callees` Returns: `SortedList<CallSite, CalleeKind>`	Mapping from a callsite to its callee kind. Returns: `SortedList<CallSite, CalleeKind>`
`this.Callers` Full Usage: `this.Callers` Returns: `HashSet<Addr>`	Callers of this function. Returns: `HashSet<Addr>`
`this.EntryPoint` Full Usage: `this.EntryPoint` Returns: `Addr`	Function entry point address. Returns: `Addr`
`this.ID` Full Usage: `this.ID` Returns: `string`	Unique ID of the function. A binary can have multiple functions with the same name, but they will have different IDs. Returns: `string`
`this.IsExternal` Full Usage: `this.IsExternal` Returns: `bool`	Whether this function is an external function. Returns: `bool`
`this.JumpTables` Full Usage: `this.JumpTables` Returns: `List<JmpTableInfo>`	Jump tables associated with this function. Returns: `List<JmpTableInfo>`
`this.Name` Full Usage: `this.Name` Returns: `string`	Name of the function. Returns: `string`
`this.NoRet` Full Usage: `this.NoRet` Returns: `NonReturningStatus`	Return the non-returning status of this function. Returns: `NonReturningStatus`
