Programs using the UNIX®-type functions must include one or more header files that contain information needed by the functions, such as:
The header files are provided in the QSYSINC library, which is optionally installable. Make sure QSYSINC is on your system before compiling programs that use these header files. For information about installing the QSYSINC library, see Include files and the QSYSINC library.
The table below shows the file and member name in the QSYSINC library for each header file used by the UNIX-type APIs in this publication.

You can display a header file in QSYSINC by using one of the following methods:
STRSEU SRCFILE(QSYSINC/H) SRCMBR(UNISTD) OPTION(5)
DSPPFM FILE(QSYSINC/SYS) MBR(STAT)
You can print a header file in QSYSINC by using one of the following methods:
STRSEU SRCFILE(QSYSINC/H) SRCMBR(UNISTD) OPTION(6)
CPYF FROMFILE(QSYSINC/SYS) TOFILE(*PRINT) FROMMBR(STAT)
Symbolic links to these header files are also provided in directory /QIBM/include.
