fgl_setenv()

Sets the value of an environment variable.

Syntax

fgl_setenv(
   name STRING,
   value STRING )
  1. name is the name of the environment variable.
  2. value is the value to be set.

Usage

The fgl_setenv() function sets or modifies the value of an environment variable.

There is a little difference between Windows® and UNIX™ platforms when passing a NULL as the value parameter. On Windows platforms, the environment variable is removed, while on UNIX, the environment variable gets an empty value (it is not removed from the environment).

Important: You may experience unexpected results if you change environment variables that are already used by the current program - for example, when you are connected to Informix® and you change the INFORMIXDIR environment variable.
