Memory Buffer Allocation Records
nnnnaaaa
indicates the internal ID of the socket being reserved.
Memory Buffer Allocation Records
This subsection describes the formatted trace records displayed when the MBUF
keyword is specified for the PTrace SELECT command. Note that there is only one
memory buffer allocation record and that each memory buffer allocation record in the
trace file is preceded by a header containing the record-type code 2.
Memory Buffer Allocation Record
The memory buffer allocation record is generated each time the NonStop TCP/IPv6
process tries to allocate memory buffers (MBUFs). Note that this record is generated
even when the allocation attempt fails.
nnnnnnnnnn
indicates the number of bytes allocated.
rrrrrrr
indicates whether the memory allocation attempt succeeded or not. The value can
be succeed or failed.
Interprocess Communication Records
This subsection describes the formatted trace records displayed when the IPC
keyword is specified for the PTrace SELECT command. Note that there is only one
interprocess communication record and that each socket system call record in the
trace file is preceded by a header containing the record-type code 3.
Socket System Call Record
The socket system call record is generated each time a socket call is made by an
application-level program.
c
indicates the socket call number being invoked. The socket call number is
described in the SYSCALH INCLUDE file.
