NAME

       Tcl_GetVersion - get the version of the library at runtime

SYNOPSIS

       #include <tcl.h>

       Tcl_GetVersion(major, minor, patchLevel, type)

ARGUMENTS

       int *major (out)                          Major version number of the Tcl library.

       int *minor (out)                          Minor version number of the Tcl library.

       int *patchLevel (out)                     The  patch level of the Tcl library (or alpha or
                                                 beta number).

       Tcl_ReleaseType *type (out)               The type of release, also indicates the type  of
                                                 patch  level.  Can  be one of TCL_ALPHA_RELEASE,

DESCRIPTION

       Tcl_GetVersion should be used to query the version number of the Tcl library  at  runtime.
       This  is  useful when using a dynamically loaded Tcl library or when writing a stubs-aware
       extension.  For instance, if you write an extension that is linked against the  Tcl  stubs
       library,  it  could  be  loaded  into a program linked to an older version of Tcl than you
       expected.  Use Tcl_GetVersion to verify that fact, and possibly to change the behavior  of
       your extension.

       Tcl_GetVersion  accepts  NULL  for  any  of the arguments. For instance if you do not care
       about the patchLevel of the library, pass a NULL for the patchLevel argument.
