		const unsigned int	n_cfg,
		unsigned char *const	buf,
		const size_t	buf_size
	)

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

Accepted configuration is set to cfg_pp.

Parameters

so_p	Pointer to a universal socket
cfg_pp	Configuration accepted
cfg_ary	Acceptable configurations
n_cfg	Number of acceptable configurations
buf	buffer for HELLO message
buf_size	size of the buffer

Returns

HIPC_SUCCESS on success, or an error on failure.

Here is the caller graph for this function:

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_p	Pointer to a universal socket
cfg_p	Acceptable configuration

Returns

HIPC_SUCCESS on success, or an error on failure.
