.SH DESCRIPTION
|
|
The
|
|
.ZN XrmInitialize
|
|
function initialize the resource manager.
|
|
It must be called before any other Xrm functions are used.
|
|
.LP
|
|
.\" $Header: XrmParse.d,v 1.7 88/08/20 10:49:05 mento Exp $
|
|
The
|
|
.ZN 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,
|
|
.ZN 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.
|
|
.LP
|
|
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.
|
|
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
|
|
.ZN 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.
|
|
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.
