working with single message frames
<constant name = "more" value = "1" />
<constant name = "reuse" value = "2" />
<constant name = "dontwait" value = "4" />
<constructor>
Create a new frame. If size is not null, allocates the frame data
to the specified size. If additionally, data is not null, copies
size octets from the specified data into the frame body.
<argument name = "data" type = "buffer" c_type = "const void *" />
<argument name = "size" type = "size" />
</constructor>
<destructor>
Destroy a frame
</destructor>
<constructor name = "new empty">
Create an empty (zero-sized) frame
</constructor>
<constructor name = "from">
Create a frame with a specified string content.
<argument name = "string" type = "string" />
</constructor>
<constructor name = "recv">
Receive frame from socket, returns zframe_t object or NULL if the recv
was interrupted. Does a blocking recv, if you want to not block then use
zpoller or zloop.
<argument name = "source" type = "sockish" />
</constructor>
<method name = "send" singleton = "1">
Send a frame to a socket, destroy frame after sending.
Return -1 on error, 0 on success.
<argument name = "self_p" type = "zframe" by_reference = "1" />
<argument name = "dest" type = "sockish" />
<argument name = "flags" type = "integer" />
<return type = "integer" />
</method>
<method name = "size">
Return number of bytes in frame data
<return type = "size" />
</method>
<method name = "data">
Return address of frame data
<return type = "buffer" mutable = "1" size = ".size" />
</method>
<method name = "meta">
Return meta data property for frame
The caller shall not modify or free the returned value, which shall be
owned by the message.
<argument name = "property" type = "string" />
<return type = "string" fresh = "0" />
</method>
<method name = "dup">
Create a new frame that duplicates an existing frame. If frame is null,
or memory was exhausted, returns null.
<return type = "zframe" fresh = "1" />
</method>
<method name = "strhex">
Return frame data encoded as printable hex string, useful for 0MQ UUIDs.
Caller must free string when finished with it.
<return type = "string" fresh = "1" />
</method>
<method name = "strdup">
Return frame data copied into freshly allocated string
Caller must free string when finished with it.
<return type = "string" fresh = "1" />
</method>
<method name = "streq">
Return TRUE if frame body is equal to string, excluding terminator
<argument name = "string" type = "string" />
<return type = "boolean" />
</method>
<method name = "more">
Return frame MORE indicator (1 or 0), set when reading frame from socket
or by the zframe_set_more() method
<return type = "integer" />
</method>
<method name = "set more">
Set frame MORE indicator (1 or 0). Note this is NOT used when sending
frame to socket, you have to specify flag explicitly.
<argument name = "more" type = "integer" />
</method>
<method name = "routing id" state = "draft" >
Return frame routing ID, if the frame came from a ZMQ_SERVER socket.
Else returns zero.
<return type = "number" size = "4" />
</method>
<method name = "set routing id" state = "draft" >
Set routing ID on frame. This is used if/when the frame is sent to a
ZMQ_SERVER socket.
<argument name = "routing id" type = "number" size = "4" />
</method>
<method name = "group" state = "draft" >
Return frame group of radio-dish pattern.
<return type = "string" />
</method>
<method name = "set group" state = "draft" >
Set group on frame. This is used if/when the frame is sent to a
ZMQ_RADIO socket.
Return -1 on error, 0 on success.
<argument name = "group" type = "string" />
<return type = "integer" />
</method>
<method name = "eq">
Return TRUE if two frames have identical size and data
If either frame is NULL, equality is always false.
<argument name = "other" type = "zframe" />
<return type = "boolean" />
</method>
<method name = "reset">
Set new contents for frame
<argument name = "data" type = "buffer" c_type = "const void *" />
<argument name = "size" type = "size" />
</method>
<method name = "print">
Send message to zsys log sink (may be stdout, or system facility as
configured by zsys_set_logstream). Prefix shows before frame, if not null.
