+/* This file includes Linux-specific support functions common to the
+ * coredumper and the thread lister; primarily, this is a collection
+ * of direct system calls, and a couple of symbols missing from
+ * standard header files.
+ * There are a few options that the including file can set to control
+ * the behavior of this file:
+ *
+ * SYS_CPLUSPLUS:
+ * The entire header file will normally be wrapped in 'extern "C" { }",
+ * making it suitable for compilation as both C and C++ source. If you
+ * do not want to do this, you can set the SYS_CPLUSPLUS macro to inhibit
+ * the wrapping. N.B. doing so will suppress inclusion of all prerequisite
+ * system header files, too. It is the caller's responsibility to provide
+ * the necessary definitions.
+ *
+ * SYS_ERRNO:
+ * All system calls will update "errno" unless overriden by setting the
+ * SYS_ERRNO macro prior to including this file. SYS_ERRNO should be
+ * an l-value.
+ *
+ * SYS_INLINE:
+ * New symbols will be defined "static inline", unless overridden by
+ * the SYS_INLINE macro.
+ *
+ * SYS_LINUX_SYSCALL_SUPPORT_H
+ * This macro is used to avoid multiple inclusions of this header file.
+ * If you need to include this file more than once, make sure to
+ * unset SYS_LINUX_SYSCALL_SUPPORT_H before each inclusion.
+ *
+ * SYS_PREFIX:
+ * New system calls will have a prefix of "sys_" unless overridden by
+ * the SYS_PREFIX macro. Valid values for this macro are [0..9] which
+ * results in prefixes "sys[0..9]_". It is also possible to set this
+ * macro to -1, which avoids all prefixes.
+ *
+ * SYS_SYSCALL_ENTRYPOINT:
+ * Some applications (such as sandboxes that filter system calls), need
+ * to be able to run custom-code each time a system call is made. If this
+ * macro is defined, it expands to the name of a "common" symbol. If
+ * this symbol is assigned a non-NULL pointer value, it is used as the
+ * address of the system call entrypoint.
+ * A pointer to this symbol can be obtained by calling
+ * get_syscall_entrypoint()
+ *
+ * This file defines a few internal symbols that all start with "LSS_".
+ * Do not access these symbols from outside this file. They are not part
+ * of the supported API.

+/* As glibc often provides subtly incompatible data structures (and implicit

+ * structures for use by the system calls.
+ * These structures have been developed by using Linux 2.6.23 headers for
+ * reference. Note though, we do not care about exact API compatibility
+ * with the kernel, and in fact the kernel often does not have a single
+ * API that works across architectures. Instead, we try to mimic the glibc
+ * API where reasonable, and only guarantee ABI compatibility with the
+ * kernel headers.
+ * Most notably, here are a few changes that were made to the structures
+ * defined by kernel headers:
+ *
+ * - we only define structures, but not symbolic names for kernel data
+ * types. For the latter, we directly use the native C datatype
+ * (i.e. "unsigned" instead of "mode_t").
+ * - in a few cases, it is possible to define identical structures for
+ * both 32bit (e.g. i386) and 64bit (e.g. x86-64) platforms by
+ * standardizing on the 64bit version of the data types. In particular,
+ * this means that we use "unsigned" where the 32bit headers say
+ * "unsigned long".
+ * - overall, we try to minimize the number of cases where we need to
+ * conditionally define different structures.
+ * - the "struct kernel_sigaction" class of structures have been
+ * modified to more closely mimic glibc's API by introducing an
+ * anonymous union for the function pointer.
+ * - a small number of field names had to have an underscore appended to
+ * them, because glibc defines a global macro by the same name.
