Function Documentation

GPRAPI int gpr_join_host_port	(	char **	out,
		const char *	host,
		int	port
	)

Given a host and port, creates a newly-allocated string of the form "host:port" or "[ho:st]:port", depending on whether the host contains colons like an IPv6 literal.

If the host is already bracketed, then additional brackets will not be added.

Usage is similar to gpr_asprintf: returns the number of bytes written (excluding the final '\0'), and *out points to a string which must later be destroyed using gpr_free().

In the unlikely event of an error, returns -1 and sets *out to NULL.

GPRAPI int gpr_split_host_port	(	const char *	name,
		char **	host,
		char **	port
	)

Given a name in the form "host:port" or "[ho:st]:port", split into hostname and port number, into newly allocated strings, which must later be destroyed using gpr_free().

Return 1 on success, 0 on failure. Guarantees *host and *port == NULL on failure.
