Subject: [PATCH] kern/misc: Split parse_printf_args() into format parsing and
|
|
|
9723a8 |
va_list handling
|
|
|
9723a8 |
|
|
|
9723a8 |
This patch is preparing for a follow up patch which will use
|
|
|
9723a8 |
the format parsing part to compare the arguments in a printf()
|
|
|
9723a8 |
format from an external source against a printf() format with
|
|
|
9723a8 |
expected arguments.
