The output is text, and +thus ends with a <newline>. The state of stdin +will remain unchanged. +.SH NOTES +.B blind-peek-head +requires that stdin is a socket, a regular file, +or a (on Linux only) a pipe. Direct pipes and +datagram sockets are supported but require that +the entire head must be written in one write. +.SH SEE ALSO +.BR blind (7), +.BR blind-read-head (1), +.BR blind-write-head (1), +.BR blind-next-frame (1) +.SH AUTHORS +Mattias Andrée +.RI < maandree@kth.se > |
