XrmInitialize(3) XLIB FUNCTIONS XrmInitialize(3)
NAME
XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind, XrmOptionDe-
scRec - initialize the Resource Manager, Resource Manager structures,
and parse the command line
SYNTAX
#include <X11/Xresource.h>
void XrmInitialize(void);
void XrmParseCommand(XrmDatabase *database, XrmOptionDescList table,
int table_count, _Xconst char *name, int *argc_in_out, char
**argv_in_out);
ARGUMENTS
argc_in_out
Specifies the number of arguments and returns the number of
remaining arguments.
argv_in_out
Specifies the command line arguments and returns the remain-
ing arguments.
database Specifies the resource database.
name Specifies the application name.
table Specifies the table of command line arguments to be parsed.
table_count
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 re-
move 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 op-
tions 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 Xrmop-
tionNoArg. The option names are compared byte-for-byte to arguments in
argv, independent of any locale. The resource values given in the ta-
ble are stored in the resource database without modification. All re-
source 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 em-
bedded 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-depen-
dent.
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 */
} XrmOptionDescRec, *XrmOptionDescList;
