In this section are found functions that do seem to fit neatly into any of the other sections.
p4_version
returns a string containing the version number of p4 being run.
p4_get_cluster_masters
This procedure fills in the values of numids and ids. It obtains the
p4-ids of all ``cluster masters'' for the program, placing them in the
ids array and placing the number of ids in numids.
p4_print_avail_buffs
P4 maintains an array of buffer lists of various sizes, so that it can very
rapidly allocate and deallocate buffers. You can see the contents of the
buffer pools at any time by calling this procedure.
buffer pool management
p4_set_avail_buff
This procedure is used to set the size of buffers in p4's buffer pools. The
parameter bufidx specifies a particular buffer list, and should be a
number from 0 to 7. The size parameter specifies that buffers up to
that size will be managed by p4 in a particular list. It is important to
maintain the buffer sizes in increasing order. The default list of buffer
sizes is 64, 256, 1024, 4096, 16384, 65536, 262144, 1048576. This causes
wasted space if you send only one large message, causing the allocation of a
large buffer which is not reused. Savings in space can be achieved by
adjusting these numbers to correspond with the message sizes of your
application. If no large messages are sent at all, however, no space is
wasted since the large buffers will never be allocated. If you send a message
larger that the largest size in this array, p4 will allocate the buffer, and
then free it back to the system as soon as it can.
