freeing up memory question..

by Matthew Shapiro · in Technical Issues · 07/27/2002 (9:44 am) · 8 replies

Sorry, this answer is escaping my mind as of this moment. If I serv_info *servers; then later on I servers = new serv_info[25]; then I want to delete say the 15th server, can i just do delete server[14];?

I think the best way to do this would be just set the 15th server to NULL, then when you are done with all the servers you "delete [] servers;"

Sounds like you want:

serv_info **servers;
servers = new serv_info* [25];
memset(servers,0,sizeof(serv_info*)*25);

//to create server 16
servers[15]= new serv_info;

//to delete server 16
delete servers[15];
servers[15]=NULL;

//to delete server array

for (int i=0;i<25;i++)
if (servers[i])
delete servers[i];

delete [] servers;

Quote:memset() does what exactly?
Initializes the memory. It basically sets the memory at location of argument 1 to the value of argument 2 which is of size argument 3.

Quote://to delete server 16
delete servers[15];
servers[15]=NULL

so basically the answer to my question is yes. But... 1 why did you initialize it by:

serv_info **servers;

Why should I use 2 *'s? btw serv_info is a struct.

thanks

To create an array of pointers that point to type serv_info.
