Function Documentation

cbdata_type cbdataInternalAddType ( cbdata_type  type,
const char *  label,
int  size 

Create a run-time registration for the class type with cbdata memory allocator.

For internal CBDATA use only.

Definition at line 197 of file cbdata.cc.

References cbdataInternalInitType(), and type.

void* cbdataInternalAlloc ( cbdata_type  type,
const char *  ,

Allocates a new entry of a registered CBDATA type.

For internal CBDATA use only.

Definition at line 224 of file cbdata.cc.

void* cbdataInternalFree ( void *  p,
const char *  ,

Frees a entry allocated by cbdataInternalAlloc().

Once this has been called cbdataReferenceValid() and cbdataReferenceValidDone() will return false regardless of whether there are remaining cbdata references.

cbdataReferenceDone() must still be called for any active references to the cbdata entry. The cbdata entry will be freed only when the last reference is removed.

For internal CBDATA use only.

int cbdataInternalReferenceDoneValid ( void **  p,
void **  tp 

Removes a reference created by cbdataReference() and checks it for validity. Meant to be used on the last dereference, usually to make a callback.

void *cbdata;
if (cbdataReferenceValidDone(reference, &cbdata)) != NULL)
callback(..., cbdata);
varThe reference variable. Will be automatically cleared to NULL.
ptrA temporary pointer to the referenced data (if valid).
