25 The master pvmd maintains a simple database, which can be used to store
26 values such as tids and make them accessible anywhere within a virtual
27 machine. This is useful when building an application such as the group
28 server, which must advertise its task id so clients can register send
29 messages to register.
30
31 The database stores integer data, indexed by <name, index> pairs. The
32 name may be any null-terminated string and the index any non-negative
33 integer. Database entries are grouped by name into classes; index may
34 be specified as -1 to store or retrieve the first available instance in
35 a class.
36
37 These functions are not part of the group library, but are the underly‐
38 ing mechanism used to implement it.

40 pvm_insert stores data at the given index. If index is -1, the data is
41 stored at the first available index in the named class, starting at 0.

47 stored, otherwise it returns a negative result. The following error
48 conditions can be returned:
