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;
