/*! \file isc/backtrace.h
 * \brief provide a back trace of the running process to help debug problems.
 *
 * This module tries to get a back trace of the process using some platform
 * dependent way when available.  It also manages an internal symbol table
 * that maps function addresses used in the process to their textual symbols.
 * This module is expected to be used to help debug when some fatal error
 * happens.
 *
 * IMPORTANT NOTE: since the (major) intended use case of this module is
 * dumping a back trace on a fatal error, normally followed by self termination,
 * functions defined in this module generally doesn't employ assertion checks
 * (if it did, a program bug could cause infinite recursive calls to a
 * backtrace function).  These functions still perform minimal checks and return
 * ISC_R_FAILURE if they detect an error, but the caller should therefore be
 * very careful about the use of these functions, and generally discouraged to
 * use them except in an exit path.  The exception is
 * isc_backtrace_getsymbolfromindex(), which is expected to be used in a
 * non-error-handling context and validates arguments with assertion checks.
