if(inputArraySize>0) {
if( !(inputLengthArray = (int*) calloc(inputArraySize, sizeof(int))) )
return -ENOMEM;
if( !(inputDirectionArray = (int*) calloc(inputArraySize, sizeof(int)))
{
free(inputLengthArray);
return -ENOMEM;
}
}
...
free(inputDirectionArray);
free(inputLengthArray);
since calloc() returns void* which must be type casted to a proper pointer
to a valid data type.
