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()

uhd::device_addr_t::device_addr_t ( const std::string &  args = "")

Create a device address from an args string.

Parameters
argsthe arguments string

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
keythe key as one of the address parameters
defthe value to use when key is not present
Returns
the casted value as type T or the default
Exceptions
errorwhen 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
