XrmMergeDatabases(3)


NAME

   XrmMergeDatabases, XrmCombineDatabase, XrmCombineFileDatabase - merge
   resource databases

SYNTAX

   #include <X11/Xresource.h>

   void XrmMergeDatabases(XrmDatabase source_db, XrmDatabase *target_db);

   void XrmCombineDatabase(XrmDatabase source_db, XrmDatabase *target_db,
          Bool override);

   Status XrmCombineFileDatabase(char *filename, XrmDatabase *target_db,
          Bool override);

ARGUMENTS

   source_db Specifies the resource database that is to be merged into the
             target database.

   target_db Specifies the resource database into which the source
             database is to be merged.

   filename  Specifies the resource database file name.

   override  Specifies whether source entries override target ones.

DESCRIPTION

   Calling the XrmMergeDatabases function is equivalent to calling the
   XrmCombineDatabase function with an override argument of True.

   The XrmCombineDatabase function merges the contents of one database
   into another.  If the same specifier is used for an entry in both
   databases, the entry in the source_db will replace the entry in the
   target_db if override is True; otherwise, the entry in source_db is
   discarded.  If target_db contains NULL, XrmCombineDatabase simply
   stores source_db in it.  Otherwise, source_db is destroyed by the
   merge, but the database pointed to by target_db is not destroyed.  The
   database entries are merged without changing values or types,
   regardless of the locales of the databases.  The locale of the target
   database is not modified.

   The XrmCombineFileDatabase function merges the contents of a resource
   file into a database.  If the same specifier is used for an entry in
   both the file and the database, the entry in the file will replace the
   entry in the database if override is True; otherwise, the entry in the
   file is discarded.  The file is parsed in the current locale.  If the
   file cannot be read, a zero status is returned; otherwise, a nonzero
   status is returned.  If target_db contains NULL, XrmCombineFileDatabase
   creates and returns a new database to it.  Otherwise, the database
   pointed to by target_db is not destroyed by the merge.  The database
   entries are merged without changing values or types, regardless of the
   locale of the database.  The locale of the target database is not
   modified.
