"dynamic memory"

[Sreekantha]

Hello,

I have a dynamically allocated array. This array is of structure type. I have a conditional check to verify whether each element of this array was allocated with memory before performing further actions. I have palced the source code below.

Initially "ParaStructArray" is allocated with defined array size

ParaStructArray = (T_Data*) calloc(arraysize, sizeof(T_Data));

Later in one fo my functions I have the validation check like this

 if(&ParaStructArray[iVal] != NULL)
 {
....

Can I know whether there exists any function similar to _msize available in Borlan compiler which can return me the information on the memory size?

1) &ParaStuctArray[iVal] has no reason to be NULL even if calloc failed (ParaStructArray must be NULL if calloc failed)
2) There is no _msize in CVI, but you can write your own. Take a look at the memory 8 bytes before the pointer you just allocated. Be warned that this is compiler/library/version dependant.

Nicolas.
