Initializes basic variables for a script.
This function is called as an initial preparation for calling a script. It sets up a number of common env. variables that will be passed to the script. For actual script calling, see script_go .
client | variables will be stored here (if null, the whole function is no-op) |

Adds parameters to environment variables for a script.
This function add details of specified lease to a list of env. variables to be passed to a script. The lease details will be prepended with specified prefix (e.g. "old_") and added to the list stored in client. Following variables may be set:
client | env. variables will be stored here |
prefix | textual prefix to be added to each variable (e.g. "old_") |
lease | lease details will be extracted from here |
Definition at line 4764 of file dhclient.c.
void script_write_requested | ( | struct client_state * | client | ) |
Write out the environent variable the client requested. Write out the environment variables for the objects that the client requested. If the object was requested the variable will be: requested_<option_name>=1 If it wasn't requested there won't be a variable.
