Linux POSIX Compliance List

I am looking for a cross-reference matrix for a list of implemented POSIX functions for a given linux kernel.

For example, I want to use linux kernel 2.6.0, but I would like to see a list of compilers for the implemented POSIX functions for this kernel. Where can I find this information?

Linux follows The standard Linux base , unlike POSIX. However, LSB is, above all, a superset of POSIX. You can find a list of all observed conflicts between LSB and POSIX here . I doubt something more detailed than what you think is necessary.

2.6.0 is a really old kernel (there are big differences since 2.6.38 ). Try using something less old.

The syscalls line page gives you a list of system calls and in which version of the kernel they appear, so it answers the question about syscalls. For the library functions, I have no idea.

In practice, Linux seems quite compatible with Posix ... And the Posix standard has also evolved.
