Function Documentation

int explain_system_on_error

(

const char *

command

)

The explain_system_on_error function is used to call the system(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_system(3) function.

This function is intended to be used in a fashion similar to the following example:

 if (explain_system_on_error(command) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

Parameters:

command

The command, exactly as to be passed to the system(3) system call.

Returns:

The value returned by the wrapped system(3) system call.
