const struct HIPC_scfg *const *const  cfg_ary,
const unsigned int  n_cfg,

)

Accepts a HIPC session if cfg_ary includes a configuration of coming HELLO message.

Accepted configuration is set to cfg_pp.

Parameters
so_pPointer to a universal socket
cfg_ppConfiguration accepted
cfg_aryAcceptable configurations
n_cfgNumber of acceptable configurations
bufbuffer for HELLO message
buf_sizesize of the buffer
Returns
HIPC_SUCCESS on success, or an error on failure.

enum HIPC_errno hipcUsocAcceptSimple ( struct HIPC_usoc *const  so_p,
const struct HIPC_scfg *const  cfg_p 
)

Accepts a HIPC session of cfg_p.

This function use the stack for a buffer, so the stack size must be large enough.

Parameters
so_pPointer to a universal socket
cfg_pAcceptable configuration
Returns
HIPC_SUCCESS on success, or an error on failure.
