VCCLCompilerTool.StructMemberAlignment Property

Specifies 1-, 2-, 4-, 8-, or 16-byte boundaries for struct member alignment. StructMemberAlignment exposes the functionality of the C++ compiler's /Zp (Struct Member Alignment) option and the MIDL compiler's MIDL Property Pages: Advanced option.

Namespace: Microsoft.VisualStudio.VCProjectEngine
Assembly: Microsoft.VisualStudio.VCProjectEngine (in microsoft.visualstudio.vcprojectengine.dll)

structMemberAlignOption StructMemberAlignment { get; set; }
/** @property */
structMemberAlignOption get_StructMemberAlignment ()

/** @property */
void set_StructMemberAlignment (/** @attribute InAttribute() */ structMemberAlignOption optSetting)

function get StructMemberAlignment () : structMemberAlignOption

function set StructMemberAlignment (optSetting : structMemberAlignOption)

Property Value

A structMemberAlignOption value.

The MIDL tool does not allow 16-byte boundaries.
