| socketSelect {base} | R Documentation |
Waits for the first of several socket connections to become available.
socketSelect(socklist, write = FALSE, timeout = NULL)
socklist |
list of open socket connections |
write |
logical. If TRUE wait for corresponding socket to
become available for writing; otherwise wait for it to become
available for reading. |
timeout |
numeric or NULL. Time in seconds to wait for a
socket to become available; NULL means wait
indefinitely. |
The values in write are recycled if necessary to make up a
logical vector the same length as socklist. Socket connections
can appear more than once in socklist; this can be useful if
you want to determine whether a socket is available for reading or
writing.
Logical the same length as socklist indicating
whether the corresponding socket connection is available for
output or input, depending on the corresponding value of write.
## Not run: ## test whether socket connection s is available for writing or reading socketSelect(list(s,s),c(TRUE,FALSE),timeout=0) ## End(Not run)
