/** \fn run_program(char *path, bool wait=true, bool root=false, bool use_elauncher=false)
|
|
Standard EDE function for running external tasks. This function is time tested
|
|
and provides a number of neat facilities.
|
|
|
|
Parameters:
|
|
\a path - Full path to executable. If path is ommited, function will search PATH
|
|
environment variable.
|
|
\a wait - If true, parent process will be frozen until program ends. If false,
|
|
it will fork into background and parent has no way to know what happened with it.
|
|
default = true
|
|
\a root - If true, sudo will be used to run program as root, with a nice facility
|
|
to enter your root password. If sudo is not available, "su -c" will be tried.
|
|
default = false
|
|
\a use_elauncher - Program will be launched through elauncher which provides busy
|
|
cursor, information about missing executable, standard output, backtrace in case
|
|
of segfault etc. However, use of elauncher may cause some minimal overhead.
|
|
Also, since there is no way to wait with elauncher, \a wait value will be
|
|
ignored. default = false
|
|
|
|
Return value of the function is program "exit value". Usually exit value of 0
|
|
means successful execution, and values 1-255 have certain special meanings
|
|
per program documentation. Several special values above 255 are:
|
|
EDERUN_NOT_FOUND - \a cmd doesn't exist
|
|
EDERUN_EMPTY - \a cmd is empty
|
|
EDERUN_NOT_EXEC - \a cmd doesn't have execute permission
|
|
EDERUN_FORK_FAILED - fork() function returned a PID of -1 (see fork(2))
|
|
EDERUN_WAITPID_FAILED - waitpid() function resulted with error (see waitpid(2))
|
|
EDERUN_EXECVE_FAILED - execve() function returned -1 (see execve(2))
|
|
EDERUN_PTY_FAILED - could not create pseudo-terminal (see getpt(3) and grantpt(3))
