Detailed Description

Mapping of key/value pairs for locating devices on the system. When left empty, the device discovery routines will search all available transports on the system (ethernet, usb...).

To narrow down the discovery process to a particular device, specify a transport key/value pair specific to your device.

• Ex, to find a usrp2: my_dev_addr["addr"] = [resolvable_hostname_or_ip]

The device address can also be used to pass arguments into the transport layer control to set (for example) buffer sizes.

An arguments string, is a way to represent a device address using a single string with delimiter characters.

• Ex: addr=192.168.10.2
• Ex: addr=192.168.10.2, recv_buff_size=1e6

Constructor & Destructor Documentation

device_addr_t() [1/2]

uhd::device_addr_t::device_addr_t

(

const std::string &

args = ""

)

Create a device address from an args string.

Parameters

args	the arguments string

device_addr_t() [2/2]

uhd::device_addr_t::device_addr_t

(

const std::map< std::string, std::string > &

info

)

Create a device address from a std::map

Parameters

info	the device info map

Member Function Documentation

cast()

template<typename T >

T uhd::device_addr_t::cast ( const std::string &  key, const T &  def  ) const

inline

Lexically cast a parameter to the specified type, or use the default value if the key is not found.

Parameters

key	the key as one of the address parameters
def	the value to use when key is not present

Returns

the casted value as type T or the default

Exceptions

error

when the parameter cannot be casted

to_pp_string()

std::string uhd::device_addr_t::to_pp_string

(

void

)

const

Convert a device address into a pretty print string.

Returns

a printable string representing the device address

to_string()

std::string uhd::device_addr_t::to_string

(

void

)

const

Convert the device address into an args string. The args string contains delimiter symbols.

Returns

a string with delimiter markup
