SYNTAX
VG_BOOL
vg4->nodelink->islink(struct VG_Nodelink *ndlnk,
const char *nodeid1,
const char *nodeid2,
VG_BOOL withdeact)
FUNCTION PARAMETERS
| ndlnk | Nodelink |
| nodeid1 | Node from |
| nodeid2 | Node to |
| withdeact | Whether ignore deactivation of links |
RETURN VALUE
Returns boolean:
- VG_TRUE: Linked
- VG_FALSE: Not linked
DESCRIPTION
Return whether nodeid1 is linked to nodeid2.
This function also returns VG_FALSE, if nodeid1 is linked to nodeid2, but this link is deactivated by vg4->nodelink->deactivate().
With withdeact set to VG_TRUE, a possible deactivation of nodeid1 to nodeid2 is ignored.
