nng_http_server_hold(3http)
NAME
nng_http_server_hold - get and hold HTTP server instance
SYNOPSIS
DESCRIPTION
The nng_http_server_hold()
acquires an instance of an HTTP server suitable
for use in serving the URL identified by url, and stores a pointer to it
at the location pointed to by serverp.
This function first looks to see if an existing HTTP server instance exists, that is suitable for this. If so, it increments the reference count on it and uses that. Otherwise, it will attempt to create a new server instance with an initial reference count of one (1).
The server instance is not started, and can have additional configuration
applied to it before it is later started with
nng_http_server_start()
.
The URL matching logic in determining servers is unable to distinguish between different aliases for the same local IP address. This may create problems when using URLs for virtual hosting. It is recommended to use canonical IP addresses or names in the url to avoid confusion. |
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_ENOMEM
|
Insufficient free memory exists. |
NNG_ENOTSUP
