|
|
// placeholders substituted with the contents of "info". For example,
|
|
// format string
|
|
// " frame %n: function %F at %S"
|
|
// will be turned into
|
|
// " frame 10: function foo::bar() at my/file.cc:10"

// You may additionally pass "strip_path_prefix" to strip prefixes of paths to
|
|
// source files and modules, and "strip_func_prefix" to strip prefixes of
|
|
// function names.
|
|
// Here's the full list of available placeholders:
|
|
// %% - represents a '%' character;
|
|
// %n - frame number (copy of frame_no);
|
|
// %p - PC in hex format;
|
|
// %m - path to module (binary or shared object);
|
|
// %o - offset in the module in hex format;
|
|
// %f - function name;
|
|
// %q - offset in the function in hex format (*if available*);
|
|
// %s - path to source file;
|
|
// %l - line in the source file;
|
|
// %c - column in the source file;
|
|
// %F - if function is known to be <foo>, prints "in <foo>", possibly
|
|
// followed by the offset in this function, but only if source file
|
|
// is unknown;
|
|
// %S - prints file/line/column information;
|
|
// %L - prints location information: file/line/column, if it is known, or
|
|
// module+offset if it is known, or (<unknown module>) string.
|
|
// %M - prints module basename and offset, if it is known, or PC.
