void GWEN_DBIO_Attach ( GWEN_DBIO dbio  ) 

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

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.

)

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

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

const char* GWEN_DBIO_GetDescription ( const GWEN_DBIO dbio  ) 

Returns a descriptive text about this particular GWEN_DBIO.

Definition at line 313 of file dbio.c.

const char* GWEN_DBIO_GetName ( const GWEN_DBIO dbio  ) 

Returns the name of a GWEN_DBIO.

Definition at line 306 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).
