NAME

       XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind, XrmOptionDe-
       scRec - initialize the Resource Manager, Resource Manager structures,
       and parse the command line

SYNTAX

       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 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
       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'' represen-
       tation 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 applica-
       tion for use in building the database entry.  The name argument is pre-
       fixed 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 implementa-
       tion-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;
