When \fBTCL_MEM_DEBUG\fR +is not defined, these functions are all no-ops. +.PP +\fBTcl_DumpActiveMemory\fR will output a list of all currently +allocated memory to the specified file. The information output for +each allocated block of memory is: starting and ending addresses +(excluding guard zone), size, source file where \fBckalloc\fR was +called to allocate the block and line number in that file. It is +especially useful to call \fBTcl_DumpActiveMemory\fR after the Tcl +interpreter has been deleted. +.PP +\fBTcl_InitMemory\fR adds the Tcl \fBmemory\fR command to the +interpreter given by \fIinterp\fR. \fBTcl_InitMemory\fR is called +by \fBTcl_Main\fR. +.PP +\fBTcl_ValidateAllMemory\fR forces a validation of the guard zones of +all currently allocated blocks of memory. Normally validation of a +block occurs when its freed, unless full validation is enabled, in +which case validation of all blocks occurs when \fBckalloc\fR and +\fBckfree\fR are called. This function forces the validation to occur +at any point. + +.SH "SEE ALSO" +TCL_MEM_DEBUG, memory + +.SH KEYWORDS +memory, debug + + |
