You may also be able to use Rprintf ?

Yes, the reason for the error is the use of sprintf. You can instead use
snprintf where n is the maximum number of bytes to write, including the
terminating nul character. For example:
char msg[8191];
snprintf(msg, 8191, "criteria: error (%d) -> %s\n", inErr, errStr);
Rf_error(msg);
or however large you made the error string.

Dear all,
I am updating a CRAN-archived R package, so it can get back to CRAN. But
there is a warning produced in Linux OS that I am not sure to understand
and I do not know how to solve, even after looking at ‘Writing portable
packages’ in the ‘Writing R Extensions’ manual and after searching in the
web. The warning is
* checking compiled code ... WARNING
File ‘ccckc/libs/ccckc.so’:
Found ‘sprintf’, possibly from ‘sprintf’ (C)
Object: ‘criteria.o’
Compiled code should not call entry points which might terminate R nor
write to stdout/stderr instead of to the console, nor use Fortran I/O
nor system RNGs nor [v]sprintf.
See ‘Writing portable packages’ in the ‘Writing R Extensions’ manual.
The package contains both C and Fortran code and in the criteria.c there
is only a sprintf use, as follows:
sprintf(msg,"criteria: error (%d) -> %s\n", inErr, errStr);
Rf_error(msg);
May be the reason of the warning the next line the ‘Writing R Extensions’
manual?
Use ofsprintfandvsprintfis regarded as a potential security risk and
warned about on some platforms.[82](
https://cran.r-project.org/doc/manuals/R-exts.html#FOOT82)R CMD
checkreports if any calls are found.
If that is the reason, is there any alternative to the use of sprintf?
Anyway, what can I do?
Thanks you in advance for your time.
Kind regards,
Iago
