56 * Stability and versioning definitions. These #defines are used in the tables
57 * of identifiers below to fill in the attribute and version fields associated
58 * with each identifier. The DT_ATTR_* macros are a convenience to permit more
59 * concise declarations of common attributes such as Stable/Stable/Common. The
60 * DT_VERS_* macros declare the encoded integer values of all versions used so
61 * far. DT_VERS_LATEST must correspond to the latest version value among all
62 * versions exported by the D compiler. DT_VERS_STRING must be an ASCII string
63 * that contains DT_VERS_LATEST within it along with any suffixes (e.g. Beta).
64 * You must update DT_VERS_LATEST and DT_VERS_STRING when adding a new version,
65 * and then add the new version to the _dtrace_versions[] array declared below.
66 * Refer to the Solaris Dynamic Tracing Guide Stability and Versioning chapters
67 * respectively for an explanation of these DTrace features and their values.
69 * NOTE: Although the DTrace versioning scheme supports the labeling and
70 * introduction of incompatible changes (e.g. dropping an interface in a
71 * major release), the libdtrace code does not currently support this.
72 * All versions are assumed to strictly inherit from one another. If
73 * we ever need to provide divergent interfaces, this will need work.

83 * The version number should be increased for every customer visible release
84 * of DTrace. The major number should be incremented when a fundamental
85 * change has been made that would affect all consumers, and would reflect
86 * sweeping changes to DTrace or the D language. The minor number should be
87 * incremented when a change is introduced that could break scripts that had
88 * previously worked; for example, adding a new built-in variable could break
89 * a script which was already using that identifier. The micro number should
90 * be changed when introducing functionality changes or major bug fixes that
91 * do not affect backward compatibility -- this is merely to make capabilities
92 * easily determined from the version number. Minor bugs do not require any
93 * modification to the version number.

149 * Table of global identifiers. This is used to populate the global identifier
150 * hash when a new dtrace client open occurs. For more info see dt_ident.h.
151 * The global identifiers that represent functions use the dt_idops_func ops
152 * and specify the private data pointer as a prototype string which is parsed
153 * when the identifier is first encountered. These prototypes look like ANSI
154 * C function prototypes except that the special symbol "@" can be used as a
155 * wildcard to represent a single parameter of any type (i.e. any dt_node_t).
156 * The standard "..." notation can also be used to represent varargs. An empty
157 * parameter list is taken to mean void (that is, no arguments are permitted).
158 * A parameter enclosed in square brackets (e.g. "[int]") denotes an optional
