unw_flush_cache(3) [debian man page]

UNW_FLUSH_CACHE(3)					       Programming Library						UNW_FLUSH_CACHE(3)

NAME
unw_flush_cache -- flush cached info SYNOPSIS
#include <libunwind.h> void unw_flush_cache(unw_addr_space_t as, unw_word_t lo, unw_word_t hi); DESCRIPTION
The unw_flush_cache() routine flushes all cached info as it relates to address-range lo to hi (non-inclusive) in the target address-space as. In addition, all info cached for address-space as that is not tied to a particular code-range is also flushed. For example, the address of the dynamic registration list is not tied to a code-range and its cached value (if any) is flushed by a call to this routine. The address range specified by lo and hi should be understood as a hint: unw_flush_cache() may flush more information than requested, but never less. In other words, unw_flush_cache() may overflush, but not underflush. As a special case, if arguments lo and hi are both 0, all information cached on behalf of address space as is flushed. RETURN VALUE
The unw_flush_cache() routine cannot fail and does not return a value. THREAD AND SIGNAL SAFETY
The unw_flush_cache() routine is thread-safe as well as safe to use from a signal handler. SEE ALSO

NAME
unw_is_fpreg -- check if a register is a floating-point register SYNOPSIS
#include <libunwind.h> int unw_is_fpreg(unw_regnum_t reg); DESCRIPTION
The unw_is_fpreg() routine checks whether register number reg is a floating-point register. This routine is normally implemented as a macro and applications should not attempt to take its address. RETURN VALUE
The unw_is_fpreg() routine returns a non-zero value if reg is a floating-point register. Otherwise, it returns a value of 0. THREAD AND SIGNAL SAFETY
unw_is_fpreg() is thread-safe as well as safe to use from a signal handler. SEE ALSO
