mrpt::system::os Namespace Reference

Detailed Description

This namespace provides a OS-independent interface to low-level functions.

Most of these functions are converted into calls to standard functions, unless we are into Visual Studio 2005 (or newer). In that case the secure version of the standard library functions (prefix "_s") are used instead.

Functions
void *	aligned_malloc (size_t bytes, size_t alignment)
	Returns an aligned memory block. More...
void *	aligned_calloc (size_t bytes, size_t alignment)
	Identical to aligned_malloc, but it zeroes the reserved memory block. More...
void *	aligned_realloc (void *old_ptr, size_t bytes, size_t alignment)
	Frees a memory block reserved by aligned_malloc. More...
void	aligned_free (void *p)
	Frees a memory block reserved by aligned_malloc. More...
template<typename _Tp >
_Tp *	align_ptr (_Tp *ptr, int n=(int) sizeof(_Tp))
	Returns a pointer a bit forward in memory so it's aligned for the given boundary size. More...
int	sprintf (char *buf, size_t bufSize, const char *format,...) noexcept MRPT_printf_format_check(3
	An OS-independent version of sprintf (Notice the bufSize param, which may be ignored in some compilers) More...
int int	vsprintf (char *buf, size_t bufSize, const char *format, va_list args) noexcept
	An OS-independent version of vsprintf (Notice the bufSize param, which may be ignored in some compilers) More...
int	vsnprintf (char *buf, size_t bufSize, const char *format, va_list args) noexcept
	An OS-independent version of vsnprintf (Notice the bufSize param, which may be ignored in some compilers) More...
FILE *	fopen (const char *fileName, const char *mode) noexcept
	An OS-independent version of fopen. More...
FILE *	fopen (const std::string &fileName, const char *mode) noexcept
	An OS-independent version of fopen (std::string version) More...
int	fprintf (FILE *fil, const char *format,...) noexcept MRPT_printf_format_check(2
	An OS-independent version of fprintf. More...
int void	fclose (FILE *f)
	An OS-independent version of fclose. More...
char *	strcat (char *dest, size_t destSize, const char *source) noexcept
	An OS-independent version of strcat. More...
char *	strcpy (char *dest, size_t destSize, const char *source) noexcept
	An OS-independent version of strcpy. More...
int	_strcmp (const char *str1, const char *str2) noexcept
	An OS-independent version of strcmp. More...
int	_strcmpi (const char *str1, const char *str2) noexcept
	An OS-independent version of strcmpi. More...
int	_strncmp (const char *str, const char *subStr, size_t count) noexcept
	An OS-independent version of strncmp. More...
int	_strnicmp (const char *str, const char *subStr, size_t count) noexcept
	An OS-independent version of strnicmp. More...
int64_t	_strtoll (const char *nptr, char **endptr, int base)
	An OS-independent version of strtoll. More...
uint64_t	_strtoull (const char *nptr, char **endptr, int base)
	An OS-independent version of strtoull. More...
time_t	timegm (struct tm *tm)
	An OS-independent version of timegm (which is not present in all compilers): converts a time structure into an UTM time_t. More...
void	memcpy (void *dest, size_t destSize, const void *src, size_t copyCount) noexcept
	An OS and compiler independent version of "memcpy". More...
int	getch () noexcept
	An OS-independent version of getch, which waits until a key is pushed. More...
bool	kbhit () noexcept
	An OS-independent version of kbhit, which returns true if a key has been pushed. More...
