XrmInitialize(3) XLIB FUNCTIONS XrmInitialize(3)
NAME XrmInitialize, XrmParseCommand, XrmValue, XrmOptionKind, XrmOptionDescRec - 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, _Xconst 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 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 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;
