NAME
rpma_mr_advise - give advice about an address range in a memory registration
SYNOPSIS
#include <librpma.h>
struct
rpma_mr_local *mr;
int
rpma_mr_advise
(struct rpma_mr_local *mr, size_t
offset, size_t len, int advice,
uint32_t flags);
DESCRIPTION
rpma_mr_advise () gives advice about an address range in a memory registration. The usage parameter specifies the operations that can be performed on the given memory address range. For available advice and flags values please see ibv_advise_mr (3).
RETURN VALUE
The rpma_mr_advise () function returns 0 on success or a negative error code on failure.
ERRORS
rpma_mr_advise () can fail with the following errors:
|
• |
RPMA_E_INVAL - in one of the following: |
•
|
the requested range is out of the memory registration bounds |
||||
|
• |
the memory registration usage does not allow the specific advice |
|||
|
• |
the flags are invalid |
|||
|
• |
RPMA_E_NOSUPP - the operation is not supported by the system
|
• |
RPMA_E_PROVIDER - ibv_mr_advise (3) failed for other errors |
