You probably mean the ble
FYI, here's the perl code to translate strcmp to strncmp...perhaps it only
needs some other regex cases.
#!/usr/bin/perl -wT
use strict;
while ()
{
if (/(strcmp\()+/)
{
if (/\((\w+)\((\w*)(\W*)(\w*)(\W*)(\w*)(\W*)(\,
)(\w*)(\W*)\)/) {

Not true. There is much C++ code which should use , strncmp or even
glib::ustring for UTF.

blenders strings are assumed to be zero terminated in many places so
using strncpy and strncmp are not especially making blenders code less
vulnerable to buffer overruns unless our own internal functions also
accept a string lengths.

Hi,
I can't see how such kind of replacement would help us. And we can't use
cstring dur to Blender is mostly written in C, not C++.

Hi,
It'd be best to rewrite the strcmp functions with strncmp and using
#include instead of libc string.h .
So strcmp(1,2) would become std::strncmp(1,2,std::strlen(2));
