Members

Functions

close int close(): Closes the BLOB. After calling this function, blob should no longer be used.
freeData void freeData(): Let the provider free any internal data stored in blob. The user is still responsible for deallocating blob itself.
getBlobStruct GdaBlob* getBlobStruct(): Undocumented in source. Be warned that the author may not have intended to support it.
getStruct void* getStruct(): the main Gtk struct as a void*
lseek int lseek(int offset, int whence): Sets the blob read/write position.
open int open(GdaBlobMode mode): Opens an existing BLOB. The BLOB must be initialized by gda_connection_create_blob or obtained from a GdaValue.
read int read(void* buf, int size, int bytesRead): Reads a chunk of bytes from the BLOB into a user-provided location.
remove int remove(): Removes the BLOB from the database. After calling this function, blob should no longer be used.
write int write(void* buf, int size, int bytesWritten): Writes a chunk of bytes from a user-provided location to the BLOB.

Variables

gdaBlob GdaBlob* gdaBlob;: the main Gtk struct
