It will then manage a set of key values that the programmer can search for. This allows programmers to save a users settings and then retrieve then at a latter time. It currently supports upto 1024 different settings. Two constructors are provided. They will dertermine what directory to look for the settings file and what the name of the file is. If the directory is not specified then a default directory of .<DEFAULT_DIR> will be created in the users home directory. A file will be created in this directory. The name will be the one specified by the caller. If none is specified then DEFAULT_FILE will be created. To retrieve and store strings into the file readValueFromFile and writeValueToFile should be called. <p><hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="aflibEnvFile::aflibEnvFile"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> aflibEnvFile::aflibEnvFile </td> <td class="md" valign="top">( </td> <td class="md" nowrap valign="top">char * </td> <td class="mdname" nowrap> <em>env_file</em>, </td> </tr> <tr> <td></td> <td></td> <td class="md" nowrap>char * </td> <td class="mdname" nowrap> <em>env_dir</em> = NULL</td> </tr> <tr> <td></td> <td class="md">) </td> <td class="md" colspan="2"></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Constructor with parameters.<p>This will create a environment directory name to use with env_dir.
