NAME
XkbCopyKeyType - Copy one XkbKeyTypeRec structures SYNOPSIS
Status XkbCopyKeyType (XkbKeyTypePtr from, XkbKeyTypePtr into); ARGUMENTS
- from pointer to XkbKeyTypeRec to be copied - into pointer to XkbKeyTypeRec to be changed DESCRIPTION
XkbCopyKeyType copies the key type specified by from to the key type specified by into. Both must point to legal XkbKeyTypeRec structures. Xkb assumes from and into point to different places. As a result, overlaps can be fatal. XkbCopyKeyType frees any existing map, preserve, and level_names in into prior to copying. If any allocation errors occur while copying from to into, XkbCopyKeyType returns BadAlloc. Oth- erwise, XkbCopyKeyType copies from to into and returns Success. 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

NAME
XkbCopyKeyTypes - Copy more than one XkbKeyTypeRec structure SYNOPSIS
Status XkbCopyKeyTypes ( from, into, num_types ) 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
