Module prctl

Expand description

Bindings for the Linux prctl system call.

There are similarities (but also differences) with FreeBSD’s procctl system call, whose interface is located in the procctl.rs file.

Structs§

FloatingPointEmulationControl: PR_FPEMU_* flags for use with floating_point_emulation_control and set_floating_point_emulation_control.
FloatingPointExceptionMode: Zero means floating point exceptions are disabled.
PrctlMmMap: This structure provides new memory descriptor map which mostly modifies /proc/pid/stat[m] output for a task. This mostly done in a sake of checkpoint/restore functionality.
SpeculationFeatureControl: PR_SPEC_* flags for use with control_speculative_feature.
SpeculationFeatureState: Zero means the processors are not vulnerable.
UnalignedAccessControl: PR_UNALIGN_* flags for use with unaligned_access_control and set_unaligned_access_control.

Enums§

DumpableBehavior: SUID_DUMP_* values for use with dumpable_behavior and set_dumpable_behavior.
EndianMode: PR_ENDIAN_* values for use with endian_mode.
FloatingPointMode: PR_FP_MODE_* values for use with floating_point_mode and set_floating_point_mode.
MachineCheckMemoryCorruptionKillPolicy: PR_MCE_KILL_* values for use with machine_check_memory_corruption_kill_policy and set_machine_check_memory_corruption_kill_policy.
PTracer: Process ptracer.
SpeculationFeature: PR_SPEC_* values for use with speculative_feature_state and control_speculative_feature.
TimeStampCounterReadability: PR_TSC_* values for use with time_stamp_counter_readability and set_time_stamp_counter_readability.
TimingMethod: PR_TIMING_* values for use with timing_method and set_timing_method.
VirtualMemoryMapAddress: PR_SET_MM_* values for use with set_virtual_memory_map_address.
