Modified Files: src/lib/libc/regex: regerror.c Log Message: regerror(3): Allow null errbuf if errbuf_size is zero. The man page says: If errbuf_size is 0, errbuf is ignored but the return value is still correct. POSIX says: If errbuf_size is 0, regerror() shall ignore the errbuf argument, and return the size of the buffer needed to hold the generated string. https://pubs.opengroup.org/onlinepubs/9699919799/functions/regerror.html from e...@google.com To generate a diff of this commit: cvs rdiff -u -r1.25 -r1.26 src/lib/libc/regex/regerror.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
