NAME

       XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind, XrmOptionDescRec - 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, 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 remaining 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 remove all recognized options.  If database contains
       NULL, XrmParseCommand 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 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.  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 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-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   */
       } XrmOptionDescRec, *XrmOptionDescList;
