.Sh DESCRIPTION
|
|
|
|
|
Returns the size in bytes of the BLOB accessible via the successfully
|
|
|
|
|
opened BLOB handle in its only argument.
|
|
|
|
|
The incremental blob I/O routines can only read or overwriting existing
|
|
|
|
|
blob content; they cannot change the size of a blob.
|
|
|
|
|
.Pp
|
|
|
|
|
This routine only works on a BLOB handle which has been
|
|
|
|
|
created by a prior successful call to sqlite3_blob_open()
|
|
|
|
|
and which has not been closed by sqlite3_blob_close().
|
|
|
|
|
Passing any other pointer in to this routine results in undefined and
|
|
|
|
|
probably undesirable behavior.
