NAME
Tcl_PkgRequire, Tcl_PkgRequireEx, Tcl_PkgPresent, Tcl_PkgPresentEx, Tcl_PkgProvide, Tcl_PkgProvideEx - package version control
SYNOPSIS
#include <tcl.h>
CONST char *
Tcl_PkgRequire(interp, name, version, exact)
CONST char *
Tcl_PkgRequireEx(interp, name, version, exact, clientDataPtr)
CONST char *
Tcl_PkgPresent(interp, name, version, exact)

Tcl_PkgPresentEx(interp, name, version, exact, clientDataPtr)
int
Tcl_PkgProvide(interp, name, version)
int
Tcl_PkgProvideEx(interp, name, version, clientData)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter where package is needed or available.
CONST char *name (in) Name of package.
CONST char *version (in) A version string consisting of one or more decimal numbers separated by dots.
int exact (in) Non-zero means that only the particular version specified by version is acceptable. Zero means that
newer versions than version are also acceptable as long as they have the same major version number
as version.
ClientData clientData (in) Arbitrary value to be associated with the package.
ClientData *clientDataPtr (out) Pointer to place to store the value associated with the matching package. It is only changed if the
pointer is not NULL and the function completed successfully.
_________________________________________________________________
DESCRIPTION
These procedures provide C-level interfaces to Tcl's package and version management facilities.
Tcl_PkgRequire is equivalent to the package require command, Tcl_PkgPresent is equivalent to the package present command, and Tcl_PkgPro-
vide is equivalent to the package provide command.
See the documentation for the Tcl commands for details on what these procedures do.
If Tcl_PkgPresent or Tcl_PkgRequire complete successfully they return a pointer to the version string for the version of the package that
is provided in the interpreter (which may be different than version); if an error occurs they return NULL and leave an error message in the
interpreter's result.
Tcl_PkgProvide returns TCL_OK if it completes successfully; if an error occurs it returns TCL_ERROR and leaves an error message in the
interpreter's result.
Tcl_PkgProvideEx, Tcl_PkgPresentEx and Tcl_PkgRequireEx allow the setting and retrieving of the client data associated with the package. In
all other respects they are equivalent to the matching functions.
