XrmInitialize(3X11) XLIB FUNCTIONS XrmInitialize(3X11)
NAME
XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind,
XrmOptionDescRec - initialize the Resource Manager,
Resource Manager structures, and parse the command line
SYNTAX
void XrmInitialize();
void XrmParseCommand(database, table, tablecount, name,
argcinout, argvinout)
XrmDatabase *database;
XrmOptionDescList table;
int tablecount;
char *name;
int *argcinout;
char **argvinout;
ARGUMENTS
argcinout
Specifies the number of arguments and returns
the number of remaining arguments.
argvinout
Specifies the command line arguments and returns
the remaining arguments.
database Specifies the resource database.
name Specifies the application name.
table Specifies the table of command line arguments to
be parsed.
tablecount
Specifies the number of entries in the table.
DESCRIPTION
The XrmInitialize function initialize the resource man-
ager. 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 recog-
nized options. If database contains NULL, XrmParseCommand
creates a new database and returns a pointer to it. Oth-
erwise, 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. The
table entries contain information on the option string,

the option name, the style of option, and a value to pro-
vide 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 mod-
ification. 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 separat-
ing (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 argu-
ment and the resourceNames are not in the Host Portable
Character Encoding the result is implementation dependent.
STRUCTURES
The XrmValue, XrmOptionKind, and XrmOptionDescRec struc-
tures contain:
typedef struct {
unsigned int size;
XPointer addr;
} XrmValue, *XrmValuePtr;
typedef enum {
XrmoptionNoArg, /* Value is specified in XrmOptionDescRec.value */
XrmoptionIsArg, /* Value is the option string itself */
XrmoptionStickyArg, /* Value is characters immediately following option */
XrmoptionSepArg, /* Value is next argument in argv */
XrmoptionResArg, /* Resource and value in next argument in argv */
XrmoptionSkipArg, /* Ignore this option and the next argument in argv */
XrmoptionSkipLine, /* Ignore this option and the rest of argv */
XrmoptionSkipNArgs /* Ignore this option and the next
XrmOptionDescRec.value arguments in argv */
} XrmOptionKind;
typedef struct {
char *option; /* Option specification string in argv */
char *specifier; /* Binding and resource name (sans application name) */
XrmOptionKind argKind;/* Which style of option it is */
XPointer value; /* Value to provide if XrmoptionNoArg or
XrmoptionSkipNArgs */
} XrmOptionDescRec, *XrmOptionDescList;
