SYNOPSIS
pcall(f,arg1,···)
DESCRIPTION
Calls function f with the given arguments in protected mode. This means that any error
inside f is not propagated; instead, pcall catches the error and returns a status code.
Its first result is the status code (a boolean), which is true if the call succeeds without errors. In such
case, pcall also returns all results from the call, after this first result.
RETURN VALUE
Returns a status code.
ERRORS
In case of any error, xpcall returns false plus the error message.
