.SH "NAME"
function::thread_indent_depth \- returns the nested\-depth of the current task
.SH "SYNOPSIS"
.sp

.SH "DESCRIPTION"
.PP
This function returns an integer equal to the nested function\-call depth starting from the outermost initial level\&. This function is useful for saving space (consumed by whitespace) in traces with long nested function calls\&. Use this function in a similar fashion to
\fBthread_indent\fR, i\&.e\&., in call\-probe, use thread_indent_depth(1) and in return\-probe, use thread_indent_depth(\-1)
