Detailed Description

The writer for a MINIDUMP_SYSTEM_INFO stream in a minidump file.

Member Function Documentation

◆ Children()

std::vector< internal::MinidumpWritable * > crashpad::MinidumpSystemInfoWriter::Children ( )
overrideprotectedvirtual

Returns the object’s children.

Note
Valid in kStateFrozen or any subsequent state.

Reimplemented from crashpad::internal::MinidumpWritable.

◆ Freeze()

bool crashpad::MinidumpSystemInfoWriter::Freeze ( )
overrideprotectedvirtual

Transitions the object from kStateMutable to kStateFrozen.

The default implementation marks the object as frozen and recursively calls Freeze() on all of its children. Subclasses may override this method to perform processing that should only be done once callers have finished populating an object with data. Typically, a subclass implementation would call RegisterRVA() or RegisterLocationDescriptor() on other objects as appropriate, because at the time Freeze() runs, the in-memory locations of RVAs and location descriptors are known and will not change for the remaining duration of an object’s lifetime.

Returns
true on success. false on failure, with an appropriate message logged.

Reimplemented from crashpad::internal::MinidumpStreamWriter.

◆ InitializeFromSnapshot()

void crashpad::MinidumpSystemInfoWriter::InitializeFromSnapshot ( const SystemSnapshot system_snapshot)

Initializes MINIDUMP_SYSTEM_INFO based on system_snapshot.

Parameters
[in]system_snapshotThe system snapshot to use as source data.
Note
Valid in kStateMutable. No mutator methods may be called before this method, and it is not normally necessary to call any mutator methods after this method.

◆ SetCPUOtherFeatures()

void crashpad::MinidumpSystemInfoWriter::SetCPUOtherFeatures ( uint64_t  features_0,
uint64_t  features_1 
)

Sets MINIDUMP_SYSTEM_INFO::Cpu::OtherCpuInfo::ProcessorFeatures.

This is only valid if SetCPUArchitecture() has been used to set the CPU architecture to an architecture other than kMinidumpCPUArchitectureX86 or kMinidumpCPUArchitectureX86Win64.

Note
This method may be called if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureAMD64.

◆ SetCPUX86AMDExtendedFeatures()

void crashpad::MinidumpSystemInfoWriter::SetCPUX86AMDExtendedFeatures ( uint32_t  extended_features)

Sets MINIDUMP_SYSTEM_INFO::Cpu::X86CpuInfo::AMDExtendedCPUFeatures.

This is only valid if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureX86 or kMinidumpCPUArchitectureX86Win64, and if SetCPUX86Vendor() or SetCPUX86VendorString() has been used to set the CPU vendor to “AuthenticAMD”.

Note
Do not call this method if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureAMD64.

◆ SetCPUX86Vendor()

void crashpad::MinidumpSystemInfoWriter::SetCPUX86Vendor ( uint32_t  ebx,
uint32_t  edx,
uint32_t  ecx 
)

Sets MINIDUMP_SYSTEM_INFO::Cpu::X86CpuInfo::VendorId.

This is only valid if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureX86 or kMinidumpCPUArchitectureX86Win64.

Parameters
[in]ebxThe first 4 bytes of the CPU vendor string, the value reported in cpuid 0 ebx.
[in]edxThe middle 4 bytes of the CPU vendor string, the value reported in cpuid 0 edx.
[in]ecxThe last 4 bytes of the CPU vendor string, the value reported by cpuid 0 ecx.
Note
Do not call this method if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureAMD64.

SetCPUX86VendorString()

◆ SetCPUX86VendorString()

void crashpad::MinidumpSystemInfoWriter::SetCPUX86VendorString ( const std::string &  vendor)

Sets MINIDUMP_SYSTEM_INFO::Cpu::X86CpuInfo::VendorId.

This is only valid if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureX86 or kMinidumpCPUArchitectureX86Win64.

Parameters
[in]vendorThe entire CPU vendor string, which must be exactly 12 bytes long.
Note
Do not call this method if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureAMD64.

SetCPUX86Vendor()

◆ SetCPUX86VersionAndFeatures()

void crashpad::MinidumpSystemInfoWriter::SetCPUX86VersionAndFeatures ( uint32_t  version,
uint32_t  features 
)

Sets MINIDUMP_SYSTEM_INFO::Cpu::X86CpuInfo::VersionInformation and MINIDUMP_SYSTEM_INFO::Cpu::X86CpuInfo::FeatureInformation.

This is only valid if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureX86 or kMinidumpCPUArchitectureX86Win64.

Note
Do not call this method if SetCPUArchitecture() has been used to set the CPU architecture to kMinidumpCPUArchitectureAMD64.

◆ SetCSDVersion()

void crashpad::MinidumpSystemInfoWriter::SetCSDVersion ( const std::string &  csd_version)

Arranges for MINIDUMP_SYSTEM_INFO::CSDVersionRva to point to a MINIDUMP_STRING containing the supplied string.

This method must be called prior to Freeze(). A CSD version is required in all MINIDUMP_SYSTEM_INFO streams. An empty string is an acceptable value.

◆ SizeOfObject()

size_t crashpad::MinidumpSystemInfoWriter::SizeOfObject ( )
overrideprotectedvirtual

Returns the amount of space that this object will consume when written to a minidump file, in bytes, not including any leading or trailing padding necessary to maintain proper alignment.

Note
Valid in kStateFrozen or any subsequent state.

Implements crashpad::internal::MinidumpWritable.

◆ StreamType()

MinidumpStreamType crashpad::MinidumpSystemInfoWriter::StreamType ( ) const
overrideprotectedvirtual

Returns an object’s stream type.

Note
Valid in any state.

Implements crashpad::internal::MinidumpStreamWriter.

◆ WriteObject()

bool crashpad::MinidumpSystemInfoWriter::WriteObject ( FileWriterInterface file_writer)
overrideprotectedvirtual

Writes the object’s content.

Parameters
[in]file_writerThe file writer to receive the object’s content.
Returns
true on success. false on error, indicating that the content could not be written to the minidump file.
Note
Valid in kStateWritable. The object will transition to kStateWritten after this method returns.

Implements crashpad::internal::MinidumpWritable.
