Detailed Description

Class for handling system utilities in Rishka applications.

The Sys class provides static methods for delaying execution, accessing system time, executing shell commands, retrieving system information, and exiting the application.

Member Function Documentation

change_dir()

bool Sys::change_dir ( char *  directory )

static

Changes the current working directory.

This static method changes the current working directory to the specified directory.

Parameters

directory

The directory to change to.

Returns

True if the directory change was successful, false otherwise.

delay()

void Sys::delay ( u64  ms )

static

Delay execution for a specified duration.

This method suspends program execution for the specified number of milliseconds.

Parameters

ms	The duration to delay in milliseconds.

exit()

void Sys::exit ( i32  code )

static

Terminate the application with an exit code.

This method terminates the application with the specified exit code.

Parameters

code	The exit code for the application.

info_num()

i64 Sys::info_num ( sysinfon_t  key )

static

Get system information as a numeric value.

This method retrieves system information specified by the key as a numeric value.

Parameters

key	The key for the system information.

Returns

The system information as a numeric value.

info_str()

string Sys::info_str ( sysinfos_t  key )

static

Get system information as a string.

This method retrieves system information specified by the key as a string representation.

Parameters

key	The key for the system information.

Returns

The system information as a string.

micros()

u64 Sys::micros ( )

static

Get the current system time in microseconds.

This method returns the current system time in microseconds since boot.

Returns

The current system time in microseconds.

millis()

u64 Sys::millis ( )

static

Get the current system time in milliseconds.

This method returns the current system time in milliseconds since boot.

Returns

The current system time in milliseconds.

random()

i64 Sys::random ( )

static

Generate a random integer value.

The random() function generates a random integer value within the range supported by the underlying hardware's random number generator. The generated random value is suitable for various applications such as cryptographic operations, simulation, and randomization tasks.

Returns

A random integer value within the supported range.

shellexec()

i64 Sys::shellexec ( string  cmdline )

static

Execute a shell command.

This method executes a shell command with the specified binary program file name, argument count, and argument array.

Parameters

program	The file name of the binary program to execute.
argc	The number of arguments in the argument array.
argv	The array of arguments for the shell command.

Returns

The exit status of the shell command.

working_dir()

string Sys::working_dir ( )

static

Retrieves the current working directory.

This static method returns the current working directory as a string.

Returns

A string representing the current working directory.
