NAME

       XrmInitialize,  XrmParseCommand,  XrmValue, XrmOptionKind, XrmOptionDe-
       scRec - 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  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"  representa-
       tion 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 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 fol-
       lowing 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 */ } XrmOp-
       tionKind;

       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,  *XrmOp-
       tionDescList;
