GenerateReport ( const FString& DiagnosticsPath
)

 Dumps all the data from crash context to the "minidump" report.
Public function void

InitFromDiagnostics ( const void* InAddress
)

 Inits the crash context from some diagnostic handler (ensure, stall, etc...)
Public function void

InitFromSignal ( int32 InSignal,
siginfo_t* InInfo,
void* InContext
)

 Inits the crash context from data provided by a signal handler.
Public function void

SetFirstCrashHandlerFrame ( uint64* ProgramCounter
)

 Sets the FirstCrashHandlerFrame only if it has not been set before
Public function void

SetType ( ECrashContextType InType
)

 Sets whether this crash represents a non-crash event like an ensure

Overridden from FGenericCrashContext

  Type Name Description
