XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind, XrmOptionDe‐
scRec - initialize the Resource Manager, Resource Manager structures,
and parse the command line
SYNTAX
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
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 function initialize the resource manager. It must be called before
any other Xrm functions are used.
The 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 rec‐
ognized options. If database contains NULL, 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. 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 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 resource‐
Names are not in the Host Portable Character Encoding the result is
implementation dependent.
STRUCTURES
The and 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;
