X3270IF(1)X3270IF(1)NAMEx3270if - command interface to x3270
SYNOPSISx3270if [ -v ] action [ ( param [ ,... ] ) ]
x3270if [ -v ] -s field
DESCRIPTIONx3270if provides an interface between x3270(1) and child
processes run with the Script() action.
x3270if performs one of two functions: passing an action
and optional parameters to x3270 for execution, or report-
ing the value of one of x3270's status fields.
The result of the command execution, or the value of the
requested status field, is written to standard output.
OPTIONS-v Turns on verbose debug messages, showing the lit-
eral data that is passed between x3270 and x3270if.
-s field
Causes 3270if to return the value of an x3270 sta-
tus field, rather than passing an action to be exe-
cuted. Field is an integer in the range 0 through
11, indicating the desired status field. The
indices and meanings of each field are documented
on the x3270-script(1) manual page.
EXIT STATUS
If the requested action succeeds, x3270if exits with sta-
tus 0. If the action fails, x3270if exits with status 1.
If there is an operational error within x3270if itself,
such as a command-line syntax error, missing environment
variable, or closed pipe, x3270if exits with status 2.
ENVIRONMENT
x3270 uses a pair of pipes for communication with each
child process. The values of the file descriptors for
these pipes are encoded as text in two environment vari-
ables, which are required by x3270if:
X3270OUTPUT
Output from x3270, input to the child process.
X3270INPUT
Input to x3270, output from the child process.
