Structure Array Pcd

PCD can be declared as C Array in DEC file

• When PCD is declared in DEC file, VOID* will be replaced by C Array.
• C Array can be basic data type array, such as UINT8[10]
• C Array can be structure array, such as TEST[20]
• C Array can be flexible array, such as TEST[] gTestPkgTokenSpaceGuid.PcdName|{0x00}|TEST[]|0x10000000
• C Array PCD value is VOID * type. C source code uses PcdGetPtr(PcdName) API to get PCD value pointer, then convert it to C array, and access the element value.
• If PCD is configured as Dynamic/DynamicEx PCD, C source code can use PcdSetPtrS(PcdName, SizeOfBuffer, Buffer) API to update PCD value.

Structure or Array PCD value as C style initialization in DEC/DSC

• Globle C structure or array can be initialized with the value.
• If PCD is declared as C Structure or Array, its value can be specified with C style value. For example: gTestPkgTokenSpaceGuid.PcdName|{CODE({ {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, {0, {0, 0, 0, 0, 0, 0, 0}}, })}
