For example, it is needed on some platforms in the -implementation of the \fBload\fR command. -It is also returned by the \fBinfo nameofexecutable\fR command. -.PP -On UNIX platforms this procedure is typically invoked as the very -first thing in the application's main program; it must be passed -\fIargv[0]\fR as its argument. It is important not to change the -working directory before the invocation. -\fBTcl_FindExecutable\fR uses \fIargv0\fR -along with the \fBPATH\fR environment variable to find the -application's executable, if possible. If it fails to find -the binary, then future calls to \fBinfo nameofexecutable\fR -will return an empty string. -.PP -On Windows platforms this procedure is typically invoked as the very -first thing in the application's main program as well; Its \fIargv[0]\fR -argument is only used to indicate whether the executable has a stderr -channel (any non-null value) or not (the value null). If \fBTcl_SetPanicProc\fR -is never called and no debugger is running, this determines whether -the panic message is sent to stderr or to a standard system dialog. -.PP -\fBTcl_GetNameOfExecutable\fR simply returns a pointer to the -internal full path name of the executable file as computed by -\fBTcl_FindExecutable\fR. This procedure call is the C API -equivalent to the \fBinfo nameofexecutable\fR command. NULL -is returned if the internal full path name has not been -computed or unknown. - -.SH KEYWORDS -binary, executable file |
