NAME

SYNOPSIS

ARGUMENTS

Tcl_Interp *interp (in)

Tcl interpreter in which to add commands.

const char *fileName (in)

For Tcl_DumpActiveMemory, name of the file to which memory information will be written. For Tcl_ValidateAllMemory, name of the file from which the call is being made (normally __FILE__).

int line (in)

Line number at which the call to Tcl_ValidateAllMemory is made (normally __LINE__).

DESCRIPTION

Tcl_DumpActiveMemory 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 Tcl_Alloc was called to allocate the block and line number in that file. It is especially useful to call Tcl_DumpActiveMemory after the Tcl interpreter has been deleted.

Tcl_InitMemory adds the Tcl memory command to the interpreter given by interp. Tcl_InitMemory is called by Tcl_Main.

Tcl_ValidateAllMemory 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 Tcl_Alloc and Tcl_Free are called. This function forces the validation to occur at any point.
