Hi all, though I haven't worked with sockets professionally, I find them interesting. I read some part of Unix Network Programming by Richard Stevens (considered to be the Bible I suppose as it is referred by everyone I ask) but the problem is the examples require a universal header unp.h which is a PIA to use.

The lackluster response here made me wonder this. I've been saddled with a device (Analog Devices 525x) that (from the data sheet, pg 16): disables the I2C interface during the internal [EEPROM] write cycle. That doesn't seem fair, as in "I'm getting off the couch now, so don't use it for a while because I let one rip in the s...
