.SH ARGUMENTS
|
|
.IP \fIsource_db\fP 1i
|
|
Specifies the resource database that is to be merged into the target database.
|
|
.IP \fItarget_db\fP 1i
|
|
Specifies the resource database into which the source
|
|
database is to be merged.
|
|
.IP \fIfilename\fP 1i
|
|
Specifies the resource database file name.
|
|
.IP \fIoverride\fP 1i
|
|
Specifies whether source entries override target ones.
|
|
.SH DESCRIPTION
|
|
Calling the
|
|
.B XrmMergeDatabases
|
|
function is equivalent to calling the
|
|
.B XrmCombineDatabase
|
|
function with an override argument of
|
|
.BR True .
|
|
.LP
|
|
The
|
|
.B 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
|
|
.BR True ;
|
|
otherwise, the entry in source_db is discarded.
|
|
If target_db contains NULL,
|
|
.B 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.
|
|
.LP
|
|
The
|
|
.B 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
|
|
.BR 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,
|
|
.B 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.
