INTERNET_BUFFERSA structure (wininet.h)

Contains both the data and header information.

Syntax

typedef struct _INTERNET_BUFFERSA {
 DWORD dwStructSize;
 struct _INTERNET_BUFFERSA *Next;
 LPCSTR lpcszHeader;
 DWORD dwHeadersLength;
 DWORD dwHeadersTotal;
 LPVOID lpvBuffer;
 DWORD dwBufferLength;
 DWORD dwBufferTotal;
 DWORD dwOffsetLow;
 DWORD dwOffsetHigh;
} INTERNET_BUFFERSA, *LPINTERNET_BUFFERSA;

Members

dwStructSize

Size of the structure, in bytes.

Next

Pointer to the next INTERNET_BUFFERS structure.

lpcszHeader

Pointer to a string value that contains the headers. This member can be NULL.

dwHeadersLength

Size of the headers, in TCHARs, if lpcszHeader is not NULL.

dwHeadersTotal

Size of the headers, if there is not enough memory in the buffer.

lpvBuffer

Pointer to the data buffer.

dwBufferLength

Size of the buffer, in bytes, if lpvBuffer is not NULL.

dwBufferTotal

Total size of the resource, in bytes.

dwOffsetLow

Reserved; do not use.

dwOffsetHigh

Reserved; do not use.

Remarks

Note  WinINet does not support server implementations. In addition, it should not be used from a service. For server implementations or services use Microsoft Windows HTTP Services (WinHTTP).

Note

The wininet.h header defines INTERNET_BUFFERS as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
