GCC documentation suggests setting the length argument to _one less_ than sizeof destination buffer in addition to terminating the string: https://gcc.gnu.org/onlinedocs/gcc-14.2.0/gcc/Warning-Options.html#index-Wstringop-truncation strncpy(trunc_s1, s1, sizeof trunc_s1 - 1); trunc_s1[sizeof trunc_s1 - 1] = '\0'; -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
