fi_control(3) Libfabric v1.15.1 fi_control(3) NAME fi_control - Perform an operation on a fabric resource. SYNOPSIS #include <rdma/fabric.h> int fi_control(struct fid *fid, int command, void *arg); int fi_alias(struct fid *fid, struct fid **alias_fid, uint64_t flags); int fi_get_val(struct fid *fid, int name, void *val); int fi_set_val(struct fid *fid, int name, void *val); ARGUMENTS fid Fabric resource command Operation to perform arg Optional argument to the command DESCRIPTION The fi_control operation is used to perform one or more operations on a fabric resource. Conceptually, fi_control is similar to the POSIX fcntl routine. The exact behavior of using fi_control depends on the fabric re- source being operated on, the specified command, and any provided arguments for the command. For specific details, see the fabric resource specific help pages noted below. fi_alias, fi_get_val, and fi_set_val are wrappers for fi_control with com- mands FI_ALIAS, FI_GET_VAL, FI_SET_VAL, respectively. fi_alias creates an alias of the specified fabric resource. fi_get_val reads the value of the named parameter associated with the fabric resource, while fi_set_val up- dates that value. Available parameter names depend on the type of the fab- ric resource and the provider in use. Providers may define provider spe- cific names in the provider extension header files ('rdma/fi_ext_*.h'). Please refer to the provider man pages for details.
