Detailed Description

Processing list of TAC structures.

Function Documentation

mtacAddTAC()

int mtacAddTAC	(	MTAC *	mtac,
		TAC *	tac )

Copy given TAC structure into MTAC list.

See also

mtacInit, mtacFree, mtacAllocate, MTAC, TAC

Returns

Returns TPCERROR status.

Parameters

mtac	Pointer to initiated MTAC structure; any old contents are preserved.
tac	Pointer to TAC structure to add.

Definition at line 121 of file mtac.c.

  {
  if(mtac==NULL || tac==NULL) return TPCERROR_FAIL;
  /* Make room for the TAC */
  int ret=mtacAllocateMore(mtac, 1); if(ret!=TPCERROR_OK) return(ret);
  /* Copy TAC into the end of the list */
  ret=tacDuplicate(tac, &mtac->tac[mtac->nr]); if(ret!=TPCERROR_OK) return(ret);
  mtac->nr++;
  return TPCERROR_OK;
}

mtacAllocate()

int mtacAllocate	(	MTAC *	mtac,
		int	nr )

Allocate memory for TACs in MTAC data structure.

See also

mtacInit, mtacFree, mtacAddTAC

Returns

Returns TPCERROR status.

Parameters

mtac	Pointer to initiated MTAC structure; any old contents are deleted. Number of TACs is kept at zero, but TACs in the list are initiated.
nr	Nr of TACs to allocate

Definition at line 56 of file mtac.c.

  {
  if(mtac==NULL) return TPCERROR_FAIL;
  /* Delete any previous contents */
  mtacFree(mtac);
  /* If no memory is requested, then just return */
  if(nr<1) return TPCERROR_OK;
  /* Allocate the list of TACs */
  mtac->tac=(TAC*)malloc(nr*sizeof(TAC));
  if(mtac->tac==NULL) return TPCERROR_OUT_OF_MEMORY;
  for(int i=0; i<nr; i++) tacInit(&mtac->tac[i]);
  mtac->_nr=nr;
  return TPCERROR_OK;
}

mtacAllocateMore()

int mtacAllocateMore	(	MTAC *	mtac,
		int	nr )

Allocate memory for more TACs in MTAC structure. Previous contents are not changed.

See also

mtacAllocate, mtacInit, mtacFree, mtacAddTAC, MTAC, TAC

Returns

Returns TPCERROR status.

Parameters

mtac	Pointer to initiated and previously allocated MTAC structure; any old contents are preserved, including nr of TACs.
nr	Nr of additional TAC structures to allocate; if structure contains unused space for requested TACs already, then nothing is done.

Definition at line 83 of file mtac.c.

  {
  if(mtac==NULL) return TPCERROR_FAIL;
 
  /* If not allocated before, then use mtacAllocate */
  if(mtac->_nr==0) return(mtacAllocate(mtac, nr));
 
  /* Check if there is enough space already */
  int newNr, addNr;
  newNr=mtac->nr + nr;
  addNr=newNr - mtac->_nr;
  if(addNr<=0) return TPCERROR_OK;
  
  /* Reallocate memory for TACC data */
  TAC *tacPtr;
  tacPtr=realloc(mtac->tac, sizeof(TAC)*newNr);
  if(tacPtr==NULL) return TPCERROR_OUT_OF_MEMORY;
  mtac->tac=tacPtr;
 
  /* Update the nr of allocated TACs and initiate new TACs */ 
  for(int i=mtac->_nr; i<newNr; i++) tacInit(&mtac->tac[i]);
  mtac->_nr=newNr;
 
  return TPCERROR_OK;

mtacFree()

void mtacFree

(

MTAC *

mtac

)

Free memory allocated for MTAC data. All contents are destroyed.

Precondition

Before first use initialize the MTAC struct with mtacInit().

Parameters

mtac	Pointer to MTAC.

Definition at line 38 of file mtac.c.

  {
  if(mtac==NULL) return;
  /* Free allocated TACs. */ 
  for(int i=0; i<mtac->_nr; i++) tacFree(&mtac->tac[i]); 
  free(mtac->tac);
  // then set everything to zero or NULL again
  mtacInit(mtac);
}
