# Create a function/macro that takes a series of named arguments. The call is
|
|
# similar to AC_DEFUN, but the setup of the function looks like this:
|
|
# UTIL_DEFUN_NAMED([MYFUNC], [FOO *BAR], [$@], [
|
|
# ... do something
|
|
# AC_MSG_NOTICE([Value of BAR is ARG_BAR])
|
|
# ])
|
|
# A star (*) in front of a named argument means that it is required and it's
|
|
# presence will be verified. To pass e.g. the first value as a normal indexed
|
|
# argument, use [m4_shift($@)] as the third argument instead of [$@]. These
|
|
# arguments are referenced in the function by their name prefixed by ARG_, e.g.
|
|
# "ARG_FOO".
|
|
#
|
|
# The generated function can be called like this:
|
|
# MYFUNC(FOO: [foo-val],
|
|
# BAR: [
|
|
# $ECHO hello world
|
|
# ])
|
|
# Note that the argument value must start on the same line as the argument name.
|
|
#
|
|
# Argument 1: Name of the function to define
|
|
# Argument 2: List of legal named arguments, with a * prefix for required arguments
|
|
# Argument 3: Argument array to treat as named, typically $@
|
|
# Argument 4: The main function body
