Writes the specified number of bytes starting at a specified offset from the
beginning of the byte array.
| ULARGE_INTEGER ulOffset,
||//Specifies the starting point for writing data
| void const *pv,
||//Points to the buffer containing the data to be written
| ULONG cb,
||//Specifies the number of bytes to write
| ULONG *pcbWritten
||//Pointer to location that contains actual number of bytes written
[in]Specifies the starting point from the beginning of the byte array for the
data to be written.
[in]Points to the buffer containing the data to be written.
[in]Specifies the number of bytes of data to attempt to write into the byte
[out]Pointer to a location where this method specifies the actual number of
bytes written to the byte array. You can set this pointer to NULL to indicate
that you are not interested in this value. In this case, this method does not
provide the actual number of bytes written.
Indicates that the specified number of bytes were written.
A general failure occurred during the write.
The caller does not have sufficient permissions for writing this byte array.
The write operation was not completed because there is no space left on the
storage device. The actual number of bytes written is still returned in pcbWritten
This method writes the specified data at the specified location in the byte
array. The number of bytes actually written is always returned in pcbWritten
, even if an error is returned. If the byte count is zero bytes, the write
operation has no effect.
is past the end of the byte array and cb
is greater than zero, ILockBytes::WriteAt
increases the size of the byte array. The fill bytes written to the byte
array are not initialized to any particular value.
