pcap_list_datalinks, pcap_free_datalinks - get a list of link-layer header types supported by a capture device, and free that list
SYNOPSIS
#include <pcap/pcap.h>
int pcap_list_datalinks(pcap_t *p, int **dlt_buf);
void pcap_free_datalinks(int *dlt_list);
DESCRIPTION
pcap_list_datalinks() is used to get a list of the supported link-layer header types of the interface associated with the pcap descriptor.
pcap_list_datalinks() allocates an array to hold the list and sets *dlt_buf to point to that array.
The caller is responsible for freeing the array with pcap_free_datalinks(), which frees the list of link-layer header types pointed to by
dlt_list.
RETURN VALUE
pcap_list_datalinks() returns the number of link-layer header types in the array on success and -1 on failure. If -1 is returned,
pcap_geterr() or pcap_perror() may be called with p as an argument to fetch or display the error text.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
