Is clGetDeviceInfo with CL_DEVICE_EXTENSIONS guaranteed to terminate its result with \0?

Doesn't seem completely clear from the docs here: https://man.opencl.org/clGetDeviceInfo.html

If not, then it wouldn't be safe to use string functions like strstr,

Upon reviewing the OpenCL 3.0 specification, I found that it does not explicitly mention whether the CL_DEVICE_EXTENSIONS string returned by clGetDeviceInfo is guaranteed to be null-terminated. The specification only states that the returned value is a "space-separated list of extension names" without specifying the null-termination.
