rpma_mr_get_descriptor - get a descriptor of a memory region
#include <librpma.h>
struct rpma_mr_local;
int rpma_mr_get_descriptor(const struct rpma_mr_local *mr, void *desc);
rpma_mr_get_descriptor() writes a network-transferable description of the provided local memory region (called 'descriptor'). Once the descriptor is transferred to the other side it should be decoded by rpma_mr_remote_from_descriptor() to create a remote memory region's structure which allows for Remote Memory Access. Please see librpma(7) for details.
The rpma_mr_get_descriptor() function returns 0 on success or a negative error code on failure.
rpma_mr_get_descriptor() can fail with the following error:
rpma_mr_get_descriptor_size(3), rpma_mr_reg(3), librpma(7) and https://pmem.io/rpma/
