PutPages Method

Uploads a range of pages to a page blob.

Syntax

ANSI (Cross Platform)
int PutPages(const char* lpszPageBlob, int64 lWriteOffset);

Unicode (Windows)
INT PutPages(LPCWSTR lpszPageBlob, LONG64 lWriteOffset);
- (void)putPages:(NSString*)pageBlob :(long long)writeOffset;
#define MID_AZUREBLOB_PUTPAGES 29

IPWORKSCLOUD_EXTERNAL int IPWORKSCLOUD_CALL IPWorksCloud_AzureBlob_Do(void *lpObj, int methid, int cparam, void *param[], int cbparam[], int64 *lpllVal);

Remarks

This method uploads a range of pages to the specified PageBlob in the container currently selected by Container, starting at the byte offset specified by WriteOffset. The uploaded data is immediately available as part of the page blob, which must already exist.

The upload data's size, in bytes, must be a multiple of 512 no larger than 4MB (4194304 bytes). The value passed for WriteOffset must also be a multiple of 512; WriteOffset % == 0.

Note that writing a page full of zeros will not actually clear said page, so it will still incur data storage charges. It is recommended that applications avoid writing pages that only contain zeros, or clear such pages using the ClearPages method.

If the specified blob has an active lease, its lease Id must be specified using LeaseId, or the request will fail.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
