# This is a utility that searches out "DECLARE_STACK_OF()"
|
|
# declarations in header files, and updates/creates/replaces
|
|
# the corresponding macro declarations that follow it. The
|
|
# reason is that with "DEBUG_SAFESTACK" defined, each type
|
|
# will generate 19 functions, all type-safe variants of the
|
|
# base "sk_***" functions for the general STACK type. Without
|
|
# DEBUG_SAFESTACK defined, we need to macro define all the
|
|
# "type'd sk_##type##_***" functions as mapping directly to
|
|
# the standard sk_*** equivalents. As it's not generally
|
|
# possible to have macros that generate macros, we need to
|
|
# control this from the "outside", here in this script.
