How to access a struct within a struct?

Can someone tell me how to do this? Just a thought that entered my mind when learning about structs. First thought was: struct one { struct two; } struct two { three; } one->two->three would this be how you would access "three"?

Struct Initialization

Hi We are using a code generator for initializing structures with the #define macro. Compiling it with the GCC 2.8.1 (with -ansi) it OK. But when we are using the SUN C 5.0 compiler it screams. Following is a code sample: #include <stdlib.h> #include <stdio.h> typedef struct TEST3 {...

IBV_CREATE_SRQ(3)					  Libibverbs Programmer's Manual					 IBV_CREATE_SRQ(3)

NAME

       ibv_create_srq, ibv_destroy_srq - create or destroy a shared receive queue (SRQ)

SYNOPSIS

       #include <infiniband/verbs.h>

       struct ibv_srq *ibv_create_srq(struct ibv_pd *pd, struct
				      ibv_srq_init_attr *srq_init_attr);

       int ibv_destroy_srq(struct ibv_srq *srq);

DESCRIPTION

       ibv_create_srq()  creates  a  shared  receive  queue  (SRQ)  associated	with  the  protection domain pd.  The argument srq_init_attr is an
       ibv_srq_init_attr struct, as defined in <infiniband/verbs.h>.

       struct ibv_srq_init_attr {
	       void		      *srq_context;    /* Associated context of the SRQ */
	       struct ibv_srq_attr     attr;	       /* SRQ attributes */
       };

       struct ibv_srq_attr {
	       uint32_t 	       max_wr;	       /* Requested max number of outstanding work requests (WRs) in the SRQ */
	       uint32_t 	       max_sge;        /* Requested max number of scatter elements per WR */
	       uint32_t 	       srq_limit;      /* The limit value of the SRQ (irrelevant for ibv_create_srq) */
       };

       The function ibv_create_srq() will update the srq_init_attr struct with the original values of the SRQ that  was  created;  the	values	of
       max_wr and max_sge will be greater than or equal to the values requested.

       ibv_destroy_srq() destroys the SRQ srq.

RETURN VALUE

       ibv_create_srq() returns a pointer to the created SRQ, or NULL if the request fails.

       ibv_destroy_srq() returns 0 on success, or the value of errno on failure (which indicates the failure reason).

NOTES

       ibv_destroy_srq() fails if any queue pair is still associated with this SRQ.
