UNW_IS_FPREG(3) 					       Programming Library						   UNW_IS_FPREG(3)

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.

UNW_GET_ACCESSORS(3)					       Programming Library					      UNW_GET_ACCESSORS(3)

NAME

       unw_get_accessors -- get pointer to accessor call-backs

SYNOPSIS

       #include <libunwind.h>

       unw_accessors_t *unw_get_accessors(unw_addr_space_t as);

DESCRIPTION

       The unw_get_accessors() routine returns a pointer to a unw_accessors_t structure, which contains the call-back routines that were specified
       when address space as was created (see unw_create_addr_space(3)).  The returned pointer is guaranteed to remain valid until  address  space
       as is destroyed by a call to unw_destroy_addr_space(3).

       Note that unw_get_accessors() can be used to retrieve the call-back routines for the local address space unw_local_addr_space.

RETURN VALUE

       The unw_get_accessors() routine cannot fail and always returns a valid (non-NULL) pointer to an unw_accessors_t structure.

THREAD AND SIGNAL SAFETY

       The unw_get_accessors() routine is thread-safe as well as safe to use from a signal handler.
