svctype = rosservice("type",svcname)
svcuri = rosservice("uri",svcname)

Description

rosservice list returns a list of service names for all of the active service servers on the ROS network.

example

rosservice info svcname returns information about the specified service, svcname.

example

rosservice type svcname returns the service type.

example

rosservice uri svcname returns the URI of the service.

example

svclist = rosservice("list") returns a list of service names for all of the active service servers on the ROS network. svclist contains a cell array of service names.

example

svcinfo = rosservice("info",svcname) returns a structure of information, svcinfo, about the service, svcname.

example

svctype = rosservice("type",svcname) returns the service type of the service as a character vector.

example

svcuri = rosservice("uri",svcname) returns the URI of the service as a character vector.
