Mapping between XRootDStatus code to Posix errno

[mpatrascoiu]

Hello,

This is a request for XRootd to provide a mapping from XRootDStatus to errno.

Currently, there is no easy way to convert the XRootDStatus.code & XRootDStatus.errNo into errno. I understand XRootd codes can't always (fully) be mapped onto errnos. However, certain clients (such as Gfal2) have to work with this.

I'm using within Gfal2 the mapping from here: XrdPosixMap.
Would it make sense to have this header public?

Cheers,
Mihai

This is hfully documented here, has been for a long time....

@abh3 : I think what @mpatrascoiu means is mapping of client error codes to errno not the protocol error codes. The XrdPosixMap::Result does exactly that so it is only the question of adding this header either to xrootd-devel or xrootd-private-devel.
