alpq(1) — USER COMMANDS
NAME
alpq − query the ALP STREAMS module
SYNOPSIS
alpq
DESCRIPTION
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 entries like the following:
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.
CAVEATS
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.
