Returns the name of the object that the symbolic link points to
Procedure:
H5G_GET_LINKVAL(loc_id, name, size, value)
Signature:
herr_t H5Gget_linkval( hid_t loc_id, const char *name, size_t size, char *value )
SUBROUTINE h5gget_linkval_f(loc_id, name, size, buffer, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: loc_id ! File or group identifier
CHARACTER(LEN=*), INTENT(IN) :: name ! Name of the symbolic link
CHARACTER(LEN=size), INTENT(OUT) :: buffer ! Buffer to hold a
! name of the object
! symbolic link points to
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5gget_linkval_f
Parameters:
hid_t loc_id | IN: Identifier of the file or group |
const char *name | IN: Symbolic link to the object whose name is to be returned |
size_t size | IN: Maximum number of characters of value to be returned |
char *value | OUT: A buffer to hold the name of the object being sought |
Description:
H5G_GET_LINKVAL returns size
characters of the name of the object that the symbolic link name
points to.
The parameter loc_id
is a file or group identifier.
The parameter name
must be a symbolic link pointing to the desired object and must be defined relative to loc_id
.
If size
is smaller than the size of the returned object name, then the name stored in the buffer value
will not be null terminated.
This function fails if name
is not a symbolic link. The presence of a symbolic link can be tested by passing zero for size
and NULL for value
.
This function should be used only after H5L_GET_INFO1 (or the deprecated function H5G_GET_OBJINFO) has been called to verify that name
is a symbolic link.
Returns:
Returns a non-negative value, with the link value in value
, if successful. Otherwise returns a negative value.
