/* File: curl_crtl_init.c
|
|
*
|
|
* This file makes sure that the DECC Unix settings are correct for
|
|
* the mode the the program is run in.
|
|
*
|
|
* The CRTL has not been initialized at the time that these routines
|
|
* are called, so many routines can not be called.
|
|
*
|
|
* This is a module that provides a LIB$INITIALIZE routine that
|
|
* will turn on some CRTL features that are not enabled by default.
|
|
*
|
|
* The CRTL features can also be turned on via logical names, but that
|
|
* impacts all programs and some aren't ready, willing, or able to handle
|
|
* those settings.
|
|
*
|
|
* On VMS versions that are too old to use the feature setting API, this
|
|
* module falls back to using logical names.
