NAME

XkbCopyKeyTypes − Copy more than one XkbKeyTypeRec structure

SYNOPSIS

Status XkbCopyKeyTypes

(XkbKeyTypePtr from, XkbKeyTypePtr into, int

num_types);

ARGUMENTS

	*− from*		pointer to array of XkbKeyTypeRecs to copy
	− into		pointer to array of XkbKeyTypeRecs to change

− num_types

number of types to copy

DESCRIPTION

XkbCopyKeyTypes copies num_types XkbKeyTypeRec structures from the array specified by from into the array specified by into. It is intended for copying between, rather than within, keyboard descriptions, so it doesn’t check for overlaps. The same rules that apply to the from and into parameters in XkbCopyKeyType apply to each entry of the from and into arrays of XkbCopyKeyTypes. If any allocation errors occur while copying from to into, XkbCopyKeyTypes returns BadAlloc. Otherwise, XkbCopyKeyTypes copies from to into and returns Success.

RETURN VALUES

Success

The XkbCopyKeyTypes function returns Success when there are no allocation errors.

STRUCTURES

Key types are used to determine the shift level of a key given the current state of the keyboard. The set of all possible key types for the Xkb keyboard description are held in the types field of the client map, whose total size is stored in size_types, and whose total number of valid entries is stored in num_types. Key types are defined using the following structure:

typedef struct { /∗ Key Type */
XkbModsRec mods; /∗ modifiers used to compute shift level */
unsigned char num_levels; /∗ total # shift levels, do not modify
directly */
unsigned char map_count; /∗ # entries in map, preserve (if non-NULL)
*/
XkbKTMapEntryPtr map; /∗ vector of modifiers for each shift level
*/
XkbModsPtr preserve; /∗ mods to preserve for corresponding map
entry */
Atom name; /∗ name of key type */
Atom * level_names; /∗ array of names of each shift level */
} XkbKeyTypeRec, *XkbKeyTypePtr;

DIAGNOSTICS

BadAlloc

Unable to allocate storage

Opportunity

Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.

Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.

Free Software

Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
