Function Documentation

int fsal2posix_openflags	(	fsal_openflags_t	fsal_flags,
		int *	p_posix_flags
	)

converts an fsal open flag to an vfs open flag.

fsal2posix_openflags: Convert FSAL open flags to Posix open flags.

Parameters:

fsal_flags	(input): The FSAL open flags to be translated.
posix_flags	(output): Pointer to the POSIX open flags.

Returns:

- ERR_FSAL_NO_ERROR (no error).

• ERR_FSAL_FAULT (posix_flags is a NULL pointer).
• ERR_FSAL_INVAL (invalid or incompatible input flags).

fsal2posix_openflags: Convert FSAL open flags to Posix open flags.

Parameters:

fsal_flags	(input): The FSAL open flags to be translated.
p_hpss_flags	(output): Pointer to the POSIX open flags.

Returns:

- ERR_FSAL_NO_ERROR (no error).

• ERR_FSAL_FAULT (p_hpss_flags is a NULL pointer).
• ERR_FSAL_INVAL (invalid or incompatible input flags).

fsal_status_t posix2fsal_attributes	(	struct stat *	p_buffstat,
		fsal_attrib_list_t *	p_fsalattr_out
	)

Converts POSIX attributes (struct stat) to FSAL attributes (fsal_attrib_list_t)

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).
