Using Built-in Variables and Statements Statement Use $hold $holdprocess $holdstopall $holdprocessstopall Holds the current process. If all other processes in the group are already held at this eval point, TotalView releases all of them. If other processes in the group are running, they continue to run. Like $hold, except that any processes in the group which are running are stopped. The other processes in the group are not automatically held by this call— they are just stopped. $holdthread Freezes the current thread, leaving other threads running. $holdthreadstop $holdthreadstopprocess Like $holdthread, except that it stops the process. The other processes in the group are left running. $holdthreadstopall Like $holdthreadstop, except that it stops the entire group. $stop $stopprocess Sets a process-level breakpoint. The process that executes this statement stops; other processes in the control group continue to execute. $stopall Sets a program-group-level breakpoint. All processes in the control group stop when any thread or process in the group executes this statement. $stopthread Sets a thread-level breakpoint. Although the thread that executes this statement stops, all other threads in the process continue to execute. If the target system cannot stop an individual thread, this statement performs the same as to $stopprocess. $visualize(expression[,slice]) Visualizes the data specified by expression and modified by the optional slice value. Expression and slice must be expressed using the code fragment’s language. The expression must return a dataset (after modification by slice) that can be visualized. slice is a quoted string that contains a slice expression. For more information on using $visualize in an expression, see “Using the Visualizer” on page 184. 396 Chapter 17: Evaluating Expressions
Glossary ACTION POINT: A debugger feature that lets a user request that program execution stop under certain conditions. Action points include breakpoints, watchpoints, eval points, and barriers. ACTION POINT IDENTIFIER: A unique integer ID associated with an action point. ACTIVATION RECORD: See stack frame. ADDRESS SPACE: A region of memory that contains code and data from a program. One or more threads can run in an address space. A process normally contains an address space. ADDRESSING EXPRESSION: A set of instructions that tell TotalView where to find information. These expressions are only used within the type transformation facility on page 410. AFFECTED P/T SET: The set of process and threads that are affected by the command. For most commands, this is identical to the target P/T set, but in some cases it might include additional threads. (See “p/t (process/thread) set” on page 405 for more information.) AGGREGATE DATA: A collection of data elements. For example, a structure or an array is an aggregate. AGGREGATED OUTPUT: The CLI compresses output from multiple threads when they would be identical except for the P/T identifier. API: Application Program Interface. The formal interface by which programs communicate with libraries. ARENA: A specifier that indicates the processes, threads, and groups upon which a command executes. Arena specifiers are p (process), t (thread), g (group), d (default), and a (all). ARRAY SECTION: In Fortran, a portion of an array that is also an array. The elements of this array is a new unnamed array object with its own indices. Compare this with a TotalView array slice on page 398. TotalView Users Guide: version 8.7 397
