Function Documentation

void GWEN_DBIO_Attach ( GWEN_DBIO dbio  ) 

Increments the internal usage counter. This counter is decremented upon GWEN_DBIO_free.

Definition at line 239 of file dbio.c.

GWEN_DBIO_CHECKFILE_RESULT GWEN_DBIO_CheckFile ( GWEN_DBIO dbio,
const char *  fname,
uint32_t  guiid,
int  msecs 
)

Checks whether the given file is supported by the given DBIO.

Definition at line 288 of file dbio.c.

GWEN_IO_LAYER io,
GWEN_DB_NODE db,
GWEN_DB_NODE params,
uint32_t  flags,
uint32_t  guiid,
int  msecs 
)

Writes data to the given GWEN_BUFFEREDIO in the format of this particular GWEN_DBIO.

void GWEN_DBIO_free ( GWEN_DBIO dbio  ) 

Releases the ressources associated with the given GWEN_DBIO if the usage counter reaches zero.

References GWEN_FREE_OBJECT, GWEN_INHERIT_FINI, and GWEN_LIST_FINI.

const char* GWEN_DBIO_GetDescription ( const GWEN_DBIO dbio  ) 

Returns a descriptive text about this particular GWEN_DBIO.

Definition at line 312 of file dbio.c.

const char* GWEN_DBIO_GetName ( const GWEN_DBIO dbio  ) 

Returns the name of a GWEN_DBIO.

Definition at line 305 of file dbio.c.

GWEN_DBIO* GWEN_DBIO_GetPlugin ( const char *  modname  ) 

This function creates a GWEN_DBIO of the given name. It therefore loads the appropriate plugin if necessary. The caller becomes the owner of the object returned, so he/she is responsible for freeing it (Note: Previous version kept the ownership so that the caller was not allowed to free the object. This has changed).

Reads data from the given io layer and stores the data read into the given DB. The stream represented by the buffered io is expected to have the format for this particular GWEN_DBIO.
