+.Dt SQLITE3_BLOB_WRITE 3
+.Os
+.Sh NAME
+.Nm sqlite3_blob_write
+.Nd write data into a BLOB incrementally
+.Sh SYNOPSIS
+.In sqlite3.h
+.Ft int
+.Fo sqlite3_blob_write
+.Fa "sqlite3_blob *"
+.Fa "const void *z"
+.Fa "int n"
+.Fa "int iOffset"
+.Fc
+.Sh DESCRIPTION
+This function is used to write data into an open BLOB handle
+from a caller-supplied buffer.
+N bytes of data are copied from the buffer Z into the open BLOB, starting
+at offset iOffset.
+.Pp
+On success, sqlite3_blob_write() returns SQLITE_OK.
+Otherwise, an error code or an extended error code
+is returned.
+Unless SQLITE_MISUSE is returned, this function sets the database connection
+error code and message accessible via
+.Fn sqlite3_errcode
+and
+.Fn sqlite3_errmsg
+and related functions.
+.Pp
+If the BLOB handle passed as the first argument was not
+opened for writing (the flags parameter to
+.Fn sqlite3_blob_open
+was zero), this function returns SQLITE_READONLY.
+.Pp
+This function may only modify the contents of the BLOB; it is not possible
+to increase the size of a BLOB using this API.
+If offset iOffset is less than N bytes from the end of the BLOB, SQLITE_ERROR
+is returned and no data is written.
+The size of the BLOB (and hence the maximum value of N+iOffset) can
+be determined using the
+.Fn sqlite3_blob_bytes
+interface.
+If N or iOffset are less than zero SQLITE_ERROR is returned
+and no data is written.
+.Pp
+An attempt to write to an expired BLOB handle fails with
+an error code of SQLITE_ABORT.
+Writes to the BLOB that occurred before the BLOB handle
+expired are not rolled back by the expiration of the handle, though
+of course those changes might have been overwritten by the statement
+that expired the BLOB handle or by other independent statements.
+.Pp
+This routine only works on a BLOB handle which has been
+created by a prior successful call to
+.Fn sqlite3_blob_open
+and which has not been closed by
+.Fn sqlite3_blob_close .
+Passing any other pointer in to this routine results in undefined and
+probably undesirable behavior.
+.Pp
+.Sh IMPLEMENTATION NOTES
+These declarations were extracted from the
+interface documentation at line 7869.
