XrmInitialize(3X11)XrmInitialize(3X11)NAME
XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind, XrmOptionDe‐
scRec - initialize the Resource Manager, Resource Manager structures,
and parse the command line
SYNOPSIS
void XrmInitialize();
void XrmParseCommand(database, table, table_count, name, argc_in_out,
argv_in_out)
XrmDatabase *database;
XrmOptionDescList table;
int table_count;
char *name;
int *argc_in_out;
char **argv_in_out;
ARGUMENTS
Specifies the number of arguments and returns the number of remaining
arguments. Specifies the command line arguments and returns the
remaining arguments. Specifies the resource database. Specifies the
application name. Specifies the table of command line arguments to be
parsed. Specifies the number of entries in the table.
DESCRIPTION
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, XrmParseCom‐
mand 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 argu‐
ments 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 com‐
pletely 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.
STRUCTURES
The XrmValue, XrmOptionKind, and XrmOptionDescRec structures 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 */ } XrmOp‐
tionDescRec, *XrmOptionDescList;
