Functions
ErrorOr< std::string >	llvm::sys::findProgramByName (StringRef Name, ArrayRef< StringRef > Paths={})
	Find the first executable file Name in Paths.
std::error_code	llvm::sys::ChangeStdinMode (fs::OpenFlags Flags)
std::error_code	llvm::sys::ChangeStdoutMode (fs::OpenFlags Flags)
std::error_code	llvm::sys::ChangeStdinToBinary ()
std::error_code	llvm::sys::ChangeStdoutToBinary ()
int	llvm::sys::ExecuteAndWait (StringRef Program, ArrayRef< StringRef > Args, std::optional< ArrayRef< StringRef > > Env=std::nullopt, ArrayRef< std::optional< StringRef > > Redirects={}, unsigned SecondsToWait=0, unsigned MemoryLimit=0, std::string *ErrMsg=nullptr, bool *ExecutionFailed=nullptr, std::optional< ProcessStatistics > *ProcStat=nullptr, BitVector *AffinityMask=nullptr)
	This function executes the program using the arguments provided.
ProcessInfo	llvm::sys::ExecuteNoWait (StringRef Program, ArrayRef< StringRef > Args, std::optional< ArrayRef< StringRef > > Env, ArrayRef< std::optional< StringRef > > Redirects={}, unsigned MemoryLimit=0, std::string *ErrMsg=nullptr, bool *ExecutionFailed=nullptr, BitVector *AffinityMask=nullptr, bool DetachProcess=false)
	Similar to ExecuteAndWait, but returns immediately.
bool	llvm::sys::commandLineFitsWithinSystemLimits (StringRef Program, ArrayRef< StringRef > Args)
	Return true if the given arguments fit within system-specific argument length limits.
bool	llvm::sys::commandLineFitsWithinSystemLimits (StringRef Program, ArrayRef< const char * > Args)
	Return true if the given arguments fit within system-specific argument length limits.
std::error_code	llvm::sys::writeFileWithEncoding (StringRef FileName, StringRef Contents, WindowsEncodingMethod Encoding=WEM_UTF8)
	Saves the UTF8-encoded contents string into the file FileName using a specific encoding.
ProcessInfo	llvm::sys::Wait (const ProcessInfo &PI, std::optional< unsigned > SecondsToWait, std::string *ErrMsg=nullptr, std::optional< ProcessStatistics > *ProcStat=nullptr, bool Polling=false)
	This function waits for the process specified by PI to finish.
void	llvm::sys::printArg (llvm::raw_ostream &OS, StringRef Arg, bool Quote)
	Print a command argument, and optionally quote it.

Variables
const char	llvm::sys::EnvPathSeparator = ':'
	This is the OS-specific separator for PATH like environment variables:
