dynamic array inside a struct

[skm376]

I am a little confused as to how I need to allocate memory for a dynamic array inside a struct. Here is the struct that I am using:

typedef struct command_t *commandPtr;

typedef struct command_t
{
char* name;
int argc;
char* argv[];
} commandT;

I declare an instance of the struct as:

commandPtr theCommand;
theCommand = (commandPtr) malloc(sizeof(c ommandT));

So, now I have an instance of the struct. But the argv array is dynamic. How do I now allocate more memory to allow for argv to be any size? Any advice would be appreciated.

Thanks,
