gtpm2m2i | Migration Guide: Program Update Tapes |
The following section discusses the migration considerations for FIFO special file support.
See the APEDIT for APAR PJ27214 for information about prerequisite APARs.
FIFO special file support builds on the infrastructure provided previously with TPF Internet server support and open systems infrastructure. See TPF Internet Server Support (APARs PJ25589 and PJ25703) and Open Systems Infrastructure (APAR PJ26188) for more information.
TPF Internet server support introduced the Internet daemon and the Trivial File Transfer Protocol (TFTP) server. To support the Internet daemon and Internet server applications, infrastructure was added that provided essential application programming interfaces (APIs), such as fork and signals, that are common in the UNIX environment and heavily used by servers on those platforms. This infrastructure enabled the servers to function, but the lack of more complete system services limited their performance and capabilities. To reduce the limitation, open systems infrastructure improved the infrastructure base with pipes, shared memory, and enhanced signal support. With FIFO special file support, this infrastructure is enhanced further. These enhancements continue to ease porting efforts and encourage development of new applications for the TPF 4.1 system.
FIFO special file support provides the following:
The following describes how FIFO special file support is implemented in the TPF 4.1 system.
The mkfifo function creates an i-node in the file system that is identified as a FIFO special file (or named pipe). You can also create a FIFO special file with the ZFILE mkfifo command.
When the FIFO special file is accessed using the standard Portable Operating System Interface for Computer Environments (POSIX) file system functions, a special device driver is started. The device driver provides functions that allow multiple independent processes to write and read concurrently from the FIFO special file.
If a read function is attempted on an empty FIFO special file and no process has the file open for writing, the read function returns a value of 0 to indicate the end of the file. When the buffer for a FIFO special file becomes full, the writer is blocked until enough data is removed from the file with a read function to allow the write function to be completed.
See the TPF C/C++ Language Support User's Guide for more information about the mkfifo function and device driver changes. See TPF Operations for more information about the ZFILE mkfifo command.
The select function enhancements allow you to specify nonsocket file descriptors, socket file descriptors, or a combination of both. If you specify both nonsocket file descriptors and socket file descriptors in a single function call, the socket file descriptors must be using TCP/IP native stack support. See TCP/IP Native Stack Support (APAR PJ26683) for more information about TCP/IP native stack support.
See the TPF C/C++ Language Support User's Guide for more information about the select function.
Syslog daemon processing is controlled by a configuration file called /etc/syslog.conf in which you define logging rules and output destinations for error messages, authorization violation messages, and trace data. The syslog daemon reads the configuration file when the daemon starts and whenever the hangup signal (SIGHUP) is received. Servers on the local system use FIFO special files to communicate with the syslog daemon. Remote servers use TCP/IP sockets.
See TPF Transmission Control Protocol/Internet Protocol for more information about the syslog daemon and the syslog daemon configuration file.

Table 848 summarizes command changes. This information is presented in alphabetic order by the name of the command. See TPF Operations for a complete description of all commnds.
Attention: Changes to commands can impact any automation
programs you are using in your complex.
Table 848. Changes to Commands for FIFO Special File Support
Command | New, Changed, or No Longer Supported? | Description of Change |
---|---|---|
ZFILE ls | Changed | Updated to display FIFO special files. |
ZFILE mkfifo | New | Added to allow you to make a FIFO special file. |
Table 849 summarizes message (offline and online messages) and system error changes.
The message IDs or system error numbers are listed in numeric order preceded by their alphabetic prefix. Some offline and online messages do not have a standard message ID. For these, the messages are presented in alphabetic order based on the initial message text; or for those messages that begin with variable information, the initial message text that follows that variable information. See Messages (System Error and Offline) and Messages (Online) for a complete description of all messages and system errors.
Attention: Changes to offline messages, online messages,
and system errors may impact any automation programs you are using in your
complex.

FIFO special files cause an increase in the use of system heap storage. Use the ZCTKA DISPLAY and the ZCTKA ALTER commands to display and change the size of system heap storage, respectively. See TPF Operations for more information about these commands.
A FIFO special file buffer consists of 2 system heap frames; multiply the number of FIFO special file buffers used by your applications by 2 to estimate the number of system heap frames needed for FIFO special file buffers. See the CORREQ macro in TPF System Generation for more information about calculating the number of frames required for your TPF 4.1 system.
