Initialize the resource manager attributes

When you call resmgr_attach(), you pass a resmgr_attr_t control structure to it. Our sample code initializes this structure like this:

/* initialize resource manager attributes */
memset(&resmgr_attr, 0, sizeof resmgr_attr);
resmgr_attr.nparts_max = 1;
resmgr_attr.msg_max_size = 2048;

In this case, we're configuring:

• how many IOV structures are available for server replies (nparts_max)
• the minimum receive buffer size (msg_max_size)

For more information, see resmgr_attach() in the QNX Neutrino C Library Reference.
