If so, it +checks the success status of the prior call, and if the conversion +failed, +.ZN XtCallConverter +returns +.ZN False +immediately; otherwise it checks the size specified in the \fIto\fP +argument and, if it is greater than or equal to the size stored in the +cache, copies the information stored in the cache into the location +specified by \fIto->addr\fP, stores the cache size into \fIto->size\fP, +and returns +.ZN True . +If the size specified in the \fIto\fP argument is smaller than the size +stored in the cache, +.ZN XtCallConverter +copies the cache size into the \fIto->size\fP and returns +.ZN False . +If the converter was registered with cache type +.ZN XtCacheNone +or no value was found in the conversion cache, +.ZN XtCallConverter +calls the converter and, if it was not registered with cache type +.ZN XtCacheNone , +enters the result into the cache. +.ZN XtCallConverter +then returns what the converter returned. +.LP +The \fIcache_ref_return\fP field specifies storage allocated by the +caller in which an opaque value will be stored. If the type converter +has been registered with the +.ZN XtCacheRefCount +modifier and if the value returned in in \fIcache_ref_return\fP is +non-NULL, then the call should store the \fIcache_ref_return\fP value +in order to decrement the reference count when the converted value +is no longer required. The \fIcache_ref_return\fP argument should be +ULL if the caller is unwilling or unable to store the value. +.SH "SEE ALSO" +XtAppReleaseCacheRefs(3Xt) +.br +\fI\*(xT\fP +.br +\fI\*(xL\fP |
