    hey guys,

    I have a newtork ip that is a long int (returned from the ntohl function) in c. When displayed on screen it comes up as hex. i want to display this as a proper ip address, therefore i (think i) need to cast it 
    char decimalip [4]
    so that i can display each element and put a . between them.

    Any ideas as to how this is done?

    all the best,

    darren

    If all you want to do is print the ip address to the standard out, printf should be able to convert from hex to decimal with the %d placeholder. Casting will not convert the numbers from hex into decimal.

    inet_ntoa function will convert it to a string.
