LLVMInstallFatalErrorHandler()

void LLVMInstallFatalErrorHandler

(

LLVMFatalErrorHandler

Handler

)

Install a fatal error handler.

By default, if LLVM detects a fatal error, it will call exit(1). This may not be appropriate in many contexts. For example, doing exit(1) will bypass many crash reporting/tracing system tools. This function allows you to install a callback that will be invoked prior to the call to exit(1).

LLVMResetFatalErrorHandler()

void LLVMResetFatalErrorHandler

(

void

)

Reset the fatal error handler.

This resets LLVM's fatal error handling behavior to the default.
