struct	jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::traits_base< FailureTraits, Args >
	The base of any trait in this file. This trait calls handle_error() if it detects a failure, otherwise returns the result of the wrapped function. More...
struct	jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::simple_report_traits< FailureTraits, Args >
	This is the default trait. More...
struct	jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::switch_traits< CaseStatements, FailureTraits, Args >
	If different operations need to be performed on different return-codes, then this trait may be used. More...

Namespaces
namespace	jmmcg
	Link with -lrt to include these functions.
namespace	jmmcg::LIBJMMCG_VER_NAMESPACE
namespace	jmmcg::LIBJMMCG_VER_NAMESPACE::syscall
	A wrapper for glibc or syscalls, etc. This function captures the return-code and if it is the specified failure-code, then according to the traits may capture any error information and throw it as an exception.
namespace	jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::private_

Macros
#define	JMMCG_SYSCALL_WRAPPER(ErrMsg, RevInfo, Fn, ...)
	Use this nasty macro to wrap calling the C-style function for which the return code is basically a "single" failure-code and a range of successful ones. More...
#define	JMMCG_SYSCALL_WRAPPER_FC(FailureCode, ErrMsg, RevInfo, Fn, ...)
#define	JMMCG_SYSCALL_WRAPPER_SWITCH(CaseLabels, ErrMsg, RevInfo, Fn, ...)
	Use this nasty macro to wrap calling the C-style function for which there may be many failure codes that need different handling for each. More...

JMMCG_SYSCALL_WRAPPER

#define JMMCG_SYSCALL_WRAPPER	(		ErrMsg,
			RevInfo,
			Fn,
			...
	)

Value:

   jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::process<   \
      jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::simple_report_traits,  \
      jmmcg::LIBJMMCG_VER_NAMESPACE::syscall::failure_traits,  \

   >(__FILE__, __LINE__, LIBJMMCG_ENQUOTE(Fn), _T(LIBJMMCG_VERSION_NUMBER), ErrMsg, Fn, __VA_ARGS__)

Use this nasty macro to wrap calling the C-style function for which the return code is basically a "single" failure-code and a range of successful ones.

Todo:

This define could be removed in C++20 with the use of std::source_location, does not work with g++ v9.2.
