Detailed Description

Static functions for retrieving information about the running process.

Member Function Documentation

Fork()

static void Process::Fork ( )

static

Duplicate the calling process.

GetCommandLine()

static std::string Process::GetCommandLine ( pid_t  pid = -1 )

static

Retrieve the command line of the process with the specified PID, or of this calling process if PID is -1 (which is the default).

GetExecutableDir()

static std::string Process::GetExecutableDir ( pid_t  pid = -1 )

static

Retrieve the directory that the process executable resides in.

For example, if the process executable is located at /usr/bin/exe, then GetExecutableDir() would return the path /usr/bin. If the specified PID is -1, then the calling process will be used.

GetExecutablePath()

static std::string Process::GetExecutablePath ( pid_t  pid = -1 )

static

Retrieve the absolute path of the process with the specified PID, or of this calling process if PID is -1 (which is the default).

This path will include the process' filename.

GetID()

static pid_t Process::GetID ( )

static

Get this process ID (PID)

GetParentID()

static pid_t Process::GetParentID ( )

static

Get the parent's process ID.

GetWorkingDir()

static std::string Process::GetWorkingDir ( pid_t  pid = -1 )

static

Retrieve the current working directory of the process.

If the specified PID is -1, then the calling process will be used.
