"Little-endian to host", and the "l" stands for "long". The "'l' stands for 'long'" is a historical artifact; in 4.2BSD (and probably earlier), there were "ntohl()" and "htonl()" routines to convert a C "long", which, at the time, was 32 bits long on 16-bit and 32-bit platforms, between "network byte order" (big-endian) and "host byte order". There were also "ntohs()" and "htons()" to convert a C "short", which was 16 bits on those platforms. > why the "24" ? 24 bits. > I guess the last "l" > in tvb_get_letohl is for little endian ? Nope, "long". ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <[email protected]> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:[email protected]?subject=unsubscribe
