 #include <coemain.h> // RResourceReader

 /**

 CTulStringResourceReader reads strings from resource without CCoeEnv.

 If resource file given to the constructor is not found, the constructor leaves.

 This module is mainly for server usage, where there is the need to read resources,

 but no CCoeEnv instance is present.     

 Usage:

 @code

 #include <platform/stringresourcereader.h>

 #include <errorres.rsg> // Resource to be read header 

 TFileName myFileName( _L("z:\\resource\\errorres.rsc") );

 CTulStringResourceReader* test = CTulStringResourceReader::NewL( myFileName );

 TPtrC buf;

 buf.Set(test-> ReadResourceString(R_ERROR_RES_GENERAL)); 

 // Note that buf will only be valid as long as CTulStringResourceReader 

 // instance is alive and no new string is read by the same instance.

 // If you need to read multiple strings, make copies.

 delete test;

 @endcode

 @publishedAll

 @released
