Let s[i] (0 ≤ i
< n
) denote the (i+1
)-th stacktrace entry in the stacktrace of the current evaluation in the current thread of execution, where n
is the count of the stacktrace entries in the stackentry.
1) Attempts to create a
basic_stacktrace
consisting of s[0], s[1], ..., s[n - 1].2) Attempts to create a
basic_stacktrace
consisting of s[m], s[m + 1], ..., s[n - 1], where m
is min(skip, n)
.3) Attempts to create a
basic_stacktrace
consisting of s[m], s[m + 1], ..., s[o - 1], where m
is min(skip, n)
and o
is min(skip + max_depth, n)
. The behavior is undefined if the skip + max_depth < skip (i.e. the mathematical result of skip + max_depth overflows).In all cases, alloc
is stored into the created basic_stacktrace
and used to allocate the storage for stacktrace entries.
Contents
[edit] Parameters
alloc
-
allocator to use for all memory allocations of the constructed
basic_stacktrace
skip
-
the number of stacktrace entries to skip
max_depth
-
the maximum depth of the stacktrace entries
[edit] Return value
If the allocation succeeds, the basic_stacktrace
described above.
Otherwise, an empty basic_stacktrace
.
