alpq - query the alp STREAMS module
The alpq command takes no arguments or options. It presents, on its
standard output, a list of the functions currently registered with the
alp STREAMS module. Information on building and using these functions is
contained in the manual entry alp(7).
The output list contains such entries as
1 Ucase (Upper to lower case converter)
The first field is a sequence number. The second field is the function's
name (by which it may be accessed), and the third field is the function's
explanation string, enclosed in parentheses.
kbdcomp(1M), kbdload(1M), alp(7), kbd(7).
The alpq command works by pushing the alp STREAMS module, querying it via
ioctl(2), and then popping it immediately; its standard input (normally
the user's TTY) must thus be a stream.
