Static analyser cppcheck says:
ixpm.c:168:7: error: Width 100 given in format string (no. 1) is larger than destination buffer 's[100]', use %99s to prevent overflowing it. [invalidScanfFormatWidth]
ixpm.c:271:3: error: Width 100 given in format string (no. 1) is larger than destination buffer 's[100]', use %99s to prevent overflowing it. [invalidScanfFormatWidth]
You are right! Thanks for mentioning and pointing me to cppcheck.
Will correct this in the next release.
Fixed in 3.5.0
