XrmInitialize(3X11) — MIT X11R4

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, 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_outSpecifies the number of arguments and returns the number of remaining arguments.

argv_in_outSpecifies a pointer to the command line arguments and returns the remaining arguments.

databaseSpecifies the resource database.

nameSpecifies the application name.

tableSpecifies the table of command line arguments to be parsed.

table_countSpecifies the number of entries in the table.

Description

The XrmInitialize function initialize the resource manager.

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.

The specified table is used to parse the command line. Recognized entries in the table are removed from argv, and entries are made in 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 XrmoptionNoArg. The argc argument specifies the number of arguments in argv and is set 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 the specification. No separating (binding) character is inserted. 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.

Structures

The XrmValue, XrmOptionKind, and XrmOptionDescRec structures contain:

typedef struct {
unsigned int size;
caddr_t addr;
} XrmValue, *XrmValuePtr;

typedef enum {
XrmoptionNoArg,        /* Value specified in
                                 XrmOptionDescRec.value */
XrmoptionIsArg,        /* Value is the option string */
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 option and next argument
                                 in argv */
XrmoptionSkipLine,     /* Ignore option and the rest of argv */
XrmoptionSkipNArgs     /* Ignore 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
                                (without application name) */
XrmOptionKind argKind; /* Which style of option it is */
caddr_t value;         /* Value to provide if XrmoptionNoArg
                                 or XrmoptionSkipNArgs */
} XrmOptionDescRec, *XrmOptionDescList;
