Fixes https://github.com/mlund/spheretree/security/code-scanning/1
To fix the problem, we need to ensure that the
strncat
function uses the remaining space in the destination buffer. This can be done by subtracting the current length of the destination string from the total buffer size and then subtracting one more to account for the null terminator.strncat
call to use the remaining space in the buffer.strncat
tosizeof(qh_qhull_command) - strlen(qh_qhull_command) - 1
