v If you use standard input to pass the Xerox resource, the command uses
the default name dfault.jsl.
Note: The pdxtblkres command does not verify that the Xerox resource
is a JSL.
If you use the -f command option, you can only block one resource at a
time.
[file ...] The name of the Xerox resource file to block. When the command blocks
the resource, it replaces the contents of the existing file with the blocked
output. If you do not specify a file name, the command reads from
standard input and writes to standard output.
You can specify more than one file. Separate the file names with spaces.
Streams used by the pdxtblkres command
The pdxtblkres command uses file descriptors while it processes Xerox resources:
If you do not specify a resource file name with the command, the
fd0 (STDIN)
command reads the deblocked resource from standard input.
fd1 (STDOUT)
If you do not specify a resource file name with the command, the
command writes the blocked resource to standard output.
fd2 (STDERR)
The command writes messages from the blocking process to
standard error.
Return codes from the pdxtblkres command
Return codes from the pdxtblkres command mean:
0
The command successfully blocked the resource.
EINVAL
An error exists with one of the command options.
ENOATTR
You specified a command option without a value.
E2BIG
You specified the -f command option and more than one input file
name.
Any other return codes that are not in this list are return codes
other
from C functions. See "Return code numbers" on page 113.
