The XrmInitialize function
initialize the resource manager. It must be called before any other Xrm
functions are used.
The XrmParseCommand function parses an (argc, argv)
pair according to the specified option table, loads recognized options
into the specified database with type ``String,'' and modifies the (argc, argv)
pair to remove all recognized options. If database contains NULL, XrmParseCommand
creates a new database and returns a pointer to it. Otherwise, entries
are added to the database specified. If a database is created, it is created
in the current locale.
The specified table is used to parse the command
line. Recognized options in the table are removed from argv, and entries
are added to the specified resource database in the order they occur in
argv. The table entries contain information on the option string, the option
name, the style of option, and a value to provide if the option kind is
XrmoptionNoArg. The option names are compared byte-for-byte to arguments
in argv, independent of any locale. The resource values given in the table
are stored in the resource database without modification. All resource database
entries are created using a ``String'' representation type. The argc argument
specifies the number of arguments in argv and is set on return to the remaining
number of arguments that were not parsed. The name argument should be the
name of your application for use in building the database entry. The name
argument is prefixed to the resourceName in the option table before storing
a database entry. The name argument is treated as a single component, even
if it has embedded periods. No separating (binding) character is inserted,
so the table must contain either a period (.) or an asterisk (*) as the
first character in each resourceName entry. To specify a more completely
qualified resource name, the resourceName entry can contain multiple components.
If the name argument and the resourceNames are not in the Host Portable
Character Encoding, the result is implementation-dependent.
The
XrmValue, XrmOptionKind, and XrmOptionDescRec structures contain:
