-== NAME
-
-nng_stream_get - get option from byte stream
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-
-int nng_stream_get_bool(nng_stream *s, const char *opt, bool *valp);
-
-int nng_stream_get_int(nng_stream *s, const char *opt, int *valp);
-
-int nng_stream_get_ms(nng_stream *s, const char *opt, nng_duration *valp);
-
-int nng_stream_get_size(nng_stream *s, const char *opt, size_t *valp);
-
-int nng_stream_get_addr(nng_stream *s, const char *opt, nng_sockaddr *valp);
-
-int nng_stream_get_string(nng_stream *s, const char *opt, char **valp);
-
-int nng_stream_get_uint64(nng_stream *s, const char *opt, uint64_t *valp);
-----
-
-== DESCRIPTION
-
-The `nng_stream_get` functions are used to retrieve option values for the
-xref:nng_stream.5.adoc[byte stream] _conn_.
-
-The actual options that may be retrieved in this way vary.
-A number of them are documented in
-xref:nng_options.5.adoc[nng_options(5)] and additional linked documents.
-
-=== Forms
-
-In all of these forms, the option _opt_ is retrieved from the connected
-byte stream _s_.
-The forms vary based on the type of the option they take.
-
-The details of the type, size, and semantics of the option will depend
-on the actual option, and will be documented with the option itself.
-
-`nng_stream_get_bool()`::
-This function is for options which take a Boolean (`bool`).
-
-`nng_stream_get_int()`::
-This function is for options which take an integer (`int`).
-
-`nng_stream_get_ms()`::
-This function is used to retrieve time
-xref:nng_duration.5.adoc[durations]
-(such as timeouts), stored as a number of milliseconds.
-(The special value ((`NNG_DURATION_INFINITE`)) means an infinite amount of time, and
-the special value ((`NNG_DURATION_DEFAULT`)) means a context-specific default.)
-
-`nng_stream_get_size()`::
-This function is used to retrieve a size,
-typically for buffer sizes, message maximum sizes, and similar options.
-
-`nng_stream_get_addr()`::
-This function is used to retrieve a
-xref:nng_sockaddr.5.adoc[socket address].
-
-`nng_stream_get_string()`::
-This function is used to retrieve a `NULL`-terminated string.
-This string is created from the source using
-xref:nng_strdup.3.adoc[`nng_strdup()`]
-and consequently must be freed by the caller using
-xref:nng_strfree.3.adoc[`nng_strfree()`] when it is no longer needed.
-
-`nng_stream_get_uint64()`::
-This function is used to retrieve a 64-bit unsigned value.
-This is typically used for identifiers, network
-numbers, and similar options.
-
-== RETURN VALUES
-
-This function returns 0 on success, and non-zero otherwise.
-
-== ERRORS
-
-[horizontal]
-`NNG_ECLOSED`:: The connection is closed.
-`NNG_EINVAL`:: There was insufficient space to receive the object.
- The amount of data actually needed is returned in _sizep_.
-`NNG_ENOTSUP`:: The option is not supported.
-`NNG_EWRITEONLY`:: The option may not read.

+## Getting Stream Options

+```c
+int nng_stream_get_bool(nng_stream *s, const char *opt, bool *valp);
+int nng_stream_get_int(nng_stream *s, const char *opt, int *valp);
+int nng_stream_get_ms(nng_stream *s, const char *opt, nng_duration *valp);

+int nng_stream_get_addr(nng_stream *s, const char *opt, nng_sockaddr *valp);
+int nng_stream_get_string(nng_stream *s, const char *opt, char **valp);

+{{hi:`nng_stream_get_ms`}}

+{{hi:`nng_stream_get_addr`}}
+{{hi:`nng_stream_get_string`}}
+{{hi:`nng_stream_get_uint64`}}
+These functions are used to obtain value of an option named _opt_ from the stream _s_, and store it in the location
+referenced by _valp_.
+
+These functions access an option as a specific type. The transport layer will have details about which options
+are available, and which type they may be accessed using.
+
+In the case of `nng_stream_get_string`, the string is created as if by [`nng_strdup`], and must be freed by
+the caller using [`nng_strfree`] when no longer needed.
