Members

Size

The size of the structure. For Windows XP, the size must be specified as 64 for x86 images.

TimeDateStamp

The date and time stamp value. The value is represented in the number of seconds elapsed since midnight (00:00:00), January 1, 1970, Universal Coordinated Time, according to the system clock. The time stamp can be printed using the C run-time (CRT) function ctime.

MajorVersion

The major version number.

MinorVersion

The minor version number.

GlobalFlagsClear

The global flags that control system behavior. For more information, see Gflags.exe.

GlobalFlagsSet

The global flags that control system behavior. For more information, see Gflags.exe.

CriticalSectionDefaultTimeout

The critical section default time-out value.

DeCommitFreeBlockThreshold

The size of the minimum block that must be freed before it is freed (de-committed), in bytes. This value is advisory.

DeCommitTotalFreeThreshold

The size of the minimum total memory that must be freed in the process heap before it is freed (de-committed), in bytes. This value is advisory.

LockPrefixTable

The VA of a list of addresses where the LOCK prefix is used. These will be replaced by NOP on single-processor systems. This member is available only for x86.

MaximumAllocationSize

The maximum allocation size, in bytes. This member is obsolete and is used only for debugging purposes.

VirtualMemoryThreshold

The maximum block size that can be allocated from heap segments, in bytes.

ProcessHeapFlags

The process heap flags. For more information, see HeapCreate.

ProcessAffinityMask

The process affinity mask. For more information, see GetProcessAffinityMask. This member is available only for .exe files.

CSDVersion

The service pack version.

DependentLoadFlags

EditList

Reserved for use by the system.

SecurityCookie

A pointer to a cookie that is used by Visual C++ or GS implementation.

SEHandlerTable

The VA of the sorted table of RVAs of each valid, unique handler in the image. This member is available only for x86.

SEHandlerCount

The count of unique handlers in the table. This member is available only for x86.
