// Purpose: POSIX sigsetjmp header
// Description: This header contains all the definitions needed to support
// the POSIX sigsetjmp/siglongjmp API under eCos.
//
// Usage: This file must be included indirectly via
// the C library setjmp.h header.

// contains three fields:

// sizeof(hal_jmp_buf) savemask value (an int)
// sizeof(hal_jmp_buf)+sizeof(int)... sigset_t containing saved mask
