/* 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
* wrapper functions that convert them), we provide our own kernel data
* 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.
