XrmMergeDatabases(3)            XLIB FUNCTIONS            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(_Xconst 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.
