Function Documentation

◆ cbdataInternalAddType()

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 117 of file cbdata.cc.

References assert, cbdata_index, cbdata_types, memPoolCreate, CBDataIndex::pool, size, xmalloc, and xrealloc().

◆ cbdataInternalAlloc()

void * cbdataInternalAlloc ( cbdata_type  type)

Allocates a new entry of a registered CBDATA type.

For internal CBDATA use only.

Definition at line 145 of file cbdata.cc.

◆ cbdataInternalFree()

void * cbdataInternalFree ( void *  p)

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.

Definition at line 203 of file cbdata.cc.

References assert, cbdataRealFree(), debugs, and cbdata::FromUserData().

◆ cbdataInternalLock()

void cbdataInternalLock ( const void *  p)

Definition at line 221 of file cbdata.cc.

References assert, debugs, cbdata::FromUserData(), and INT_MAX.

Referenced by logfile_mod_daemon_open().

◆ cbdataInternalReferenceDoneValid()

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)))
callback(..., cbdata);
#define cbdataReferenceValidDone(var, ptr)
Definition: cbdata.h:239
Definition: cbdata.cc:38
varThe reference variable. Will be automatically cleared to nullptr
ptrA temporary pointer to the referenced data (if valid).

Definition at line 282 of file cbdata.cc.

References cbdataInternalUnlock(), and cbdataReferenceValid().

◆ cbdataInternalUnlock()

void cbdataInternalUnlock ( const void *  p)

◆ cbdataRealFree()

static void cbdataRealFree ( cbdata c)

Definition at line 173 of file cbdata.cc.

References cbdata_htable, cbdataCount, cbdata::data, and debugs.

Referenced by cbdataInternalFree(), and cbdataInternalUnlock().

◆ cbdataReferenceValid()

int cbdataReferenceValid ( const void *  p)
pA cbdata entry reference pointer.
Return values
0A reference is stale. The pointer refers to a entry already freed.
trueThe reference is valid and active.
