In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...
The size of a (full) trace is linear to the program's instruction path length, making it somewhat impractical. A trace may therefore be initiated at one point in a program and terminated at another point to limit the output. An ongoing interaction with the hypervisor (continuous or periodic monitoring via on-screen display for instance)
The stack is often used to store variables of fixed length local to the currently active functions. Programmers may further choose to explicitly use the stack to store local data of variable length. If a region of memory lies on the thread's stack, that memory is said to have been allocated on the stack, i.e. stack-based memory allocation (SBMA).
Specifying a filter of syscall names that should be traced (via the -e trace= option): by name, like clone,fork,vfork; using one of the predefined groups, like %ipc or %file; or (since strace 4.17) using regular expression syntax, like -e trace=/clock_.*. Specifying a list of paths to be traced (-P /etc/ld.so.cache, for example).
A debugger might use this capability to single step through a program, providing the means for a programmer to monitor the execution of the program under test. By installing a custom handler for the trace exception, it is possible to gain control of the microprocessor between the execution of normal program flow instructions. A typical trace ...

This image shows the byte stream structure of a SEG-Y file, with rev 1 Extended Textual File Header records. Since the first SEG-Y standard was published, many companies dealing with seismic data have produced variants of the SEG-Y standard which have run contrary to the aims of defining a standard for universal interchange, thus generally causing confusion and delay when data received by a ...
