Xlib Programming Manual: Creating and Storing Databases 15.4 Creating and Storing Databases A resource database is an opaque type, XrmDatabase. Each database value is stored in an XrmValue structure. This structure consists of a size, an address, and a representation type. The size is specified in bytes. The representation type is a way for you to store data tagged by some application-defined type (for example, the strings ``font'' or ``color''). It has nothing to do with the C data type or with its class. The XrmValue structure is defined as: typedef struct { unsigned int size; XPointer addr; } XrmValue, *XrmValuePtr; To initialize the resource manager, use XrmInitialize(). To retrieve a database from disk, use XrmGetFileDatabase(). To store a copy of a database to disk, use XrmPutFileDatabase(). To obtain a pointer to the screen independent resources of a display, use XResourceManagerString(). To obtain a pointer to the screen-specific resources of a screen, use XScreenResourceString(). To create a database from a string, use XrmGetStringDatabase(). To obtain locale name of a database, use XrmLocaleOfDatabase(). To destroy a resource database and free its allocated memory, use XrmDestroyDatabase(). To associate a resource database with a display, use XrmSetDatabase(). To get the resource database associated with a display, use XrmGetDatabase(). Next: Merging Resource Databases Christophe Tronche, ch.tronche@computer.org
