PCAP_DATALINK_NAME_TO_VAL(3)

💖 NAME — pcap_datalink_name_to_val in the Library Functions Manual 💖

okay so bestie, this is pcap_datalink_name_to_val, and it's here to get the link-layer header type value corresponding to a header type name. That's the whole NAME section, no cap.

✨ SYNOPSIS ✨

#include <pcap/pcap.h>

int pcap_datalink_name_to_val(const char *name);

🦋 DESCRIPTION 🦋

pcap_datalink_name_to_val() translates a link-layer header type name — specifically a DLT_ name with the DLT_ removed — to the corresponding link-layer header type value. The translation is case-insensitive, so capitalization is literally not the vibe check here.

🔥 RETURN VALUE 🔥

On success, pcap_datalink_name_to_val() returns the type value. If the name is not a known type name, it returns PCAP_ERROR — that's the "nope, don't know her" answer.
