XrmMergeDatabases(3X11) XLIB FUNCTIONS XrmMergeDatabases(3X11)
NAME
XrmMergeDatabases, XrmCombineDatabase, XrmCombineFileData-
base - merge resource databases
SYNTAX
void XrmMergeDatabases(XrmDatabase source_db, *target_db);
void XrmCombineDatabase(XrmDatabase source_db, XrmDatabase
*target_db);
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 cal-
ling the XrmCombineDatabase function with an override argu-
ment 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; oth-
erwise, 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 data-
base 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, XrmCombineFileData-
base creates and returns a new database to it. Otherwise,
the database pointed to by target_db is not destroyed by the

values or types, regardless of the locale of the database.
The locale of the target database is not modified.
