.SH ARGUMENTS
|
| 20 |
|
|
.AS Tcl_PackageInitProc *safeInitProc
|
| 21 |
|
|
.AP Tcl_Interp *interp in
|
| 22 |
|
|
If not NULL, points to an interpreter into which the package has
|
| 23 |
|
|
already been loaded (i.e., the caller has already invoked the
|
| 24 |
|
|
appropriate initialization procedure). NULL means the package
|
| 25 |
|
|
hasn't yet been incorporated into any interpreter.
|
| 26 |
|
|
.AP char *pkgName in
|
| 27 |
|
|
Name of the package; should be properly capitalized (first letter
|
| 28 |
|
|
upper-case, all others lower-case).
|
| 29 |
|
|
.AP Tcl_PackageInitProc *initProc in
|
| 30 |
|
|
Procedure to invoke to incorporate this package into a trusted
|
| 31 |
|
|
interpreter.
|
| 32 |
|
|
.AP Tcl_PackageInitProc *safeInitProc in
|
| 33 |
|
|
Procedure to call to incorporate this package into a safe interpreter
|
| 34 |
|
|
(one that will execute untrusted scripts). NULL means the package
|
| 35 |
|
|
can't be used in safe interpreters.

.SH DESCRIPTION
|
| 39 |
|
|
.PP
|
| 40 |
|
|
This procedure may be invoked to announce that a package has been
|
| 41 |
|
|
linked statically with a Tcl application and, optionally, that it
|
| 42 |
|
|
has already been loaded into an interpreter.
|
| 43 |
|
|
Once \fBTcl_StaticPackage\fR has been invoked for a package, it
|
| 44 |
|
|
may be loaded into interpreters using the \fBload\fR command.
|
| 45 |
|
|
\fBTcl_StaticPackage\fR is normally invoked only by the \fBTcl_AppInit\fR
|
| 46 |
|
|
procedure for the application, not by packages for themselves
|
| 47 |
|
|
(\fBTcl_StaticPackage\fR should only be invoked for statically
|
| 48 |
|
|
loaded packages, and code in the package itself should not need
|
| 49 |
|
|
to know whether the package is dynamically or statically loaded).
|
| 50 |
|
|
.PP
|
| 51 |
|
|
When the \fBload\fR command is used later to load the package into
|
| 52 |
|
|
an interpreter, one of \fIinitProc\fR and \fIsafeInitProc\fR will
|
| 53 |
|
|
be invoked, depending on whether the target interpreter is safe
|
| 54 |
|
|
or not.
|
| 55 |
|
|
\fIinitProc\fR and \fIsafeInitProc\fR must both match the
|
| 56 |
|
|
following prototype:
|
| 57 |
|
|
.CS
|
| 58 |
|
|
typedef int Tcl_PackageInitProc(Tcl_Interp *\fIinterp\fR);
|
| 59 |
|
|
.CE
|
| 60 |
|
|
The \fIinterp\fR argument identifies the interpreter in which the
|
| 61 |
|
|
package is to be loaded. The initialization procedure must return
|
| 62 |
|
|
\fBTCL_OK\fR or \fBTCL_ERROR\fR to indicate whether or not it completed
|
| 63 |
|
|
successfully; in the event of an error it should set \fIinterp->result\fR
|
| 64 |
|
|
to point to an error message.
|
| 65 |
|
|
The result or error from the initialization procedure will be returned
|
| 66 |
|
|
as the result of the \fBload\fR command that caused the
|
| 67 |
|
|
initialization procedure to be invoked.
