This repository is a place for C and C++ samples created with gcc for IBM i and Linux
Build command:
g++ grepsrclib.cpp -o grepsrclib
If you want the program to reside with the other packages from open source package management, copy the compiled object to the /QOpenSys/pkgs/bin directory. The final object path will be: /QOpenSys/pkgs/bin/grepsrclib
Parameters:
-l Source library name pattern to scan
-f Source file name pattern to scan
-m Source member name pattern to scan
-s String value to scan for (case insensitive)
Sample usage to scan QCLSRC in QGPL library:
grepsrclib -l "QGPL" -f "QCLSRC" -m "*" -s "monmsg"
This program is a good example of passing parameters to a command line C++ program.
Build command:
g++ parmtest1.cpp -o parmtest1
Parameters:
--file - Input file name
--outputfile - Output file name
Sample usage:
parmtest1 --file "/tmp/input.txt" -outputfile "/tmp/output.txt"
This program is a good example of calling the PING CL command from a c program.
Useful since PASE does not have a ping command.
Build command:
gcc pingi.c -o pingi
Parameters:
parm1 = host name or IP address to ping.
Sample usage:
pingi "8.8.8.8"
