function drupal_uninstall_modules in Drupal 7

Uninstalls a given list of disabled modules.

Parameters

string[] $module_list: The modules to uninstall. It is the caller's responsibility to ensure that all modules in this list have already been disabled before this function is called.

bool $uninstall_dependents: (optional) If TRUE, the function will check that all modules which depend on the passed-in module list either are already uninstalled or contained in the list, and it will ensure that the modules are uninstalled in the correct order. This incurs a significant performance cost, so use FALSE if you know $module_list is already complete and in the correct order. Defaults to TRUE.

Return value

bool Returns TRUE if the operation succeeds or FALSE if it aborts due to an unsafe condition, namely, $uninstall_dependents is TRUE and a module in $module_list has dependents which are not already uninstalled and not also included in $module_list).
