BLOB structure (wtypesbase.h)

  • Article

The BLOB structure, derived from Binary Large Object, contains information about a block of data.

Syntax

typedef struct tagBLOB {
  ULONG cbSize;
  BYTE  *pBlobData;
} BLOB, *LPBLOB;

Members

cbSize

Size of the block of data pointed to by pBlobData, in bytes.

pBlobData

Pointer to a block of data.

Remarks

The structure name BLOB comes from the acronym BLOB, which stands for Binary Large Object.

This structure does not describe the nature of the data pointed to by pBlobData.

Note  Windows Sockets defines a similar BLOB structure in Wtypes.h. Using both header files in the same source code file creates redefinition–compile time errors.
