Environment variables specific to the z/OS XL C/C++ library

The following z/OS® XL C/C++ specific environment variables are supported to provide various functions. z/OS XL C/C++ variables have the prefix _CEE_ or _EDC_. You should not use these prefixes to name your own variables.

There are no default settings for the environment variables that begin with _EDC_. There are, however, default actions that occur if these environment variables are undefined or are set to invalid values. See the descriptions of each variable below.

The z/OS XL C/C++ specific environment variables may be set with the setenv() function.
