int posix2fsal_error

(

int

posix_errorcode

)

posix2fsal_error : Convert POSIX error codes to FSAL error codes.

Parameters:

posix_errorcode

(input): The error code returned from POSIX.

Returns:

The FSAL error code associated to posix_errorcode.

Todo:

: The EBADF error also happens when file is opened for reading, and we try writting in it. In this case, we return ERR_FSAL_NOT_OPENED, but it doesn't seems to be a correct error translation.

Warning:

AIX returns EEXIST where BSD uses ENOTEMPTY; We want ENOTEMPTY to be interpreted anyway on AIX plateforms. Thus, we explicitely write its value (87).
