Detailed Description

Data structure passed for dr_register_kernel_xfer_event().

Field Documentation

◆ sig

int _dr_kernel_xfer_info_t::sig

For DR_XFER_SIGNAL_DELIVERY and DR_XFER_SIGNAL_RETURN, the signal number.

◆ source_mcontext

const dr_mcontext_t* _dr_kernel_xfer_info_t::source_mcontext

The source machine context which is about to be changed. This may be NULL if it is unknown, which is the case for DR_XFER_CALLBACK_DISPATCHER. For DR_XFER_RSEQ_ABORT, due to the constraints of handling restartable sequences, the abort PC will point prior to the committing store, while that store already executed during instrumentation. We recommend that clients treat the store as never-executed in that situation, if possible, to produce a more-representative sequence.

◆ target_pc

app_pc _dr_kernel_xfer_info_t::target_pc

The target program counter of the transfer. To obtain the full target state, call dr_get_mcontext(). (For efficiency purposes, only frequently needed state is included by default.)

◆ target_xsp

reg_t _dr_kernel_xfer_info_t::target_xsp

The target stack pointer of the transfer. To obtain the full target state, call dr_get_mcontext(). (For efficiency purposes, only frequently needed state is included by default.)

◆ type

dr_kernel_xfer_type_t _dr_kernel_xfer_info_t::type

The type of event.
