* Routines for controlled update/initialization of request structures.

|
|
* request_init() initializes its argument. Pointers and string-valued members
|
|
* are initialized to zero, to indicate that no lookup has been attempted.
|
|
*
|
|
* request_set() adds information to an already initialized request structure.

|
*
|
|
* Both functions take a variable-length name-value list.
|
|
*
|
|
* Diagnostics are reported through syslog(3).
