This command sets a hardware execution breakpoint at a specific
location and subsequently deletes it when the breakpoint is hit.
You can also specify a conditional breakpoint by using an if statement
that stops only when the conditional expression evaluates to true.
Note
The number of hardware breakpoints are usually limited. If you run out of hardware breakpoints then delete or disable one that you are no longer using.
Breakpoints that are set within a shared object are deleted when the shared object is unloaded.
Syntaxthbreak -d -p [ [filename:]location | *address] [thread thread_num...] [if expression]
Where:
dDisables the breakpoint immediately after creation.
pSpecifies whether or not the resolution of an unrecognized breakpoint location results in a pending breakpoint being created.
filenameSpecifies the file.
locationSpecifies the location:
line_numis a line number.
functionis a function name.
labelis a label name.
+offset|-offsetSpecifies the line offset from the current location.
addressSpecifies the address. This can be either an address or an expression that evaluates to an address.
expressionSpecifies an expression that is evaluated when the breakpoint is hit.
If no arguments are specified then a hardware breakpoint is set at the next instruction.
