The initialization procedure must return +\fBTCL_OK\fR or \fBTCL_ERROR\fR to indicate whether or not it completed +successfully; in the event of an error it should set \fIinterp->result\fR +to point to an error message. +The result or error from the initialization procedure will be returned +as the result of the \fBload\fR command that caused the +initialization procedure to be invoked. + +.SH KEYWORDS +initialization procedure, package, static linking |
