dynamic memory allocation in functions

[amitk3553]

I had function call
hci_host_data_pkt_gen(0x03, &data_ll_hci_rx[2], &hci_host_data_pkt_arr[2])

But execution stops after printing of "Mem locations"


Please tell me the mistake?

 unsigned char* hci_host_data_pkt_arr ;
 unsigned char* data_ll_hci_rx;
 data_ll_hci_rx= new(nothrow) unsigned char [10];

 unsigned char* hci_host_data_pkt_gen(int con_handle_lsb, unsigned char* source_location, unsigned char* dest_location)   
 {
    hci_host_data_pkt_arr = new(nothrow) unsigned char [10];
    hci_host_data_pkt_arr[0] = 0x02; 	                            
    hci_host_data_pkt_arr[1] = con_handle_lsb; 	                    
  
    cpy_ll_hci_pyld_hci_host_pyld(source_location, dest_location, 8);
                                            //!info
    return hci_host_data_pkt_arr;    
 }

void cpy_ll_hci_pyld_hci_host_pyld(unsigned char* source_location, unsigned char* dest_location, int no_mem_locations)               
 {  
    int i;  
  
    for(i=0;i<no_mem_locations;i++)
    {
             cout<<"@"<<sc_time_stamp()<<"\tMem locations------------";                                                
             dest_location[i] = source_location[i];
          
[b]/*---------------Problem is with above statement, execution stops after printing Mem Locations-------*/  [/b] 
             cout<<"@"<<sc_time_stamp()<<"\tCHECK EVENTS for data packets--";                                         
    }
 }  */

I would omit that nothrow. If you can't alloc the required memory your program is doomed anyway so it's ok end the program.

The issue is: Does dest_location and/or source_location point to something valid (i.e. at least 8 unsigned char)?

[amitk3553]

I checked for dest_location and source_location

Actually the problem is with dest_location. Source_location is working fine.

I replaced dest_location with unsigned char* a (locally declared in cpy_ll_hci_pyld_hci_host_pyld). Then it works well...it seems somewhere problem is with hci_host_data_pkt_arr(dest_location)

But I am not able to figure out
