NAME

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

SYNTAX

void XrmInitialize(void); void XrmParseCommand(XrmDatabase *_d_a_t_a_b_a_s_e, XrmOptionDescList _t_a_b_l_e, int _t_a_b_l_e___c_o_u_n_t, char *_n_a_m_e, int *_a_r_g_c___i_n___o_u_t, char **_a_r_g_v___i_n___o_u_t);

ARGUMENTS

_a_r_g_c___i_n___o_u_t Specifies the number of arguments and returns the number of remaining arguments.
_a_r_g_v___i_n___o_u_t Specifies the command line arguments
and returns the remaining arguments.
_d_a_t_a_b_a_s_e Specifies the resource database.
_n_a_m_e Specifies the application name.
_t_a_b_l_e Specifies the table of command line arguments to be parsed.
_t_a_b_l_e___c_o_u_n_t Specifies the number of entries in the table.

DESCRIPTION

The _X_r_m_I_n_i_t_i_a_l_i_z_e function initialize the resource manager. It must be called before any other Xrm functions are used.

The _X_r_m_P_a_r_s_e_C_o_m_m_a_n_d 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, _X_r_m_P_a_r_s_e_C_o_m_m_a_n_d 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 _X_r_m_o_p_t_i_o_n_N_o_A_r_g. 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 _X_r_m_V_a_l_u_e, _X_r_m_O_p_t_i_o_n_K_i_n_d, and _X_r_m_O_p_t_i_o_n_D_e_s_c_R_e_c 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;
