SYNTAX

       #include <X11/Xresource.h>

       void XrmInitialize(void);

       void XrmParseCommand(XrmDatabase *database, XrmOptionDescList table, int  table_count,  char  *name,  int

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;
