Migrate C struct to Delphi record

I would like to know how to convert C struct to Delphi record?

The following code is in C. I want to convert to Delphi.

typedef struct
  {
  Uint16        value1[32];
  Uint16        value2[22];
  Uint16        value3[8];    
  }MY_STRUCT_1;

Thanks in advance.

You might need to used the packed keyword. Delphi, by default, will align variables based on (I believe) whether you're developing on a 16, 32 or 64 bit platform and what data types are within your record. Using packed will change the length/size of memory required to hold the record. C will pack the structure by default.

MY_STRUCT_1 = packed record
  value1 : Array [0..31] of Word;
  value2 : Array [0..21] of Word;
  value3 : Array [0..7] of Word;
end;

The Uint16 is equivalent to the Word type and the [] indicates an array.

MY_STRUCT_1 = record
  value1 : Array [0..31] of Word;
  value2 : Array [0..21] of Word;
  value3 : Array [0..7] of Word;
end;
