# gl_WARN_ON_USE_PREPARE(INCLUDES, NAMES)
|
|
# ---------------------------------------
|
|
# For each whitespace-separated element in the list of NAMES, define
|
|
# HAVE_RAW_DECL_name if the function has a declaration among INCLUDES
|
|
# even after being undefined as a macro.
|
|
#
|
|
# See warn-on-use.h for some hints on how to poison function names, as
|
|
# well as ideas on poisoning global variables and macros. NAMES may
|
|
# include global variables, but remember that only functions work with
|
|
# _GL_WARN_ON_USE. Typically, INCLUDES only needs to list a single
|
|
# header, but if the replacement header pulls in other headers because
|
|
# some systems declare functions in the wrong header, then INCLUDES
|
|
# should do likewise.
|
|
#
|
|
# It is generally safe to assume declarations for functions declared
|
|
# in the intersection of C89 and C11 (such as printf) without
|
|
# needing gl_WARN_ON_USE_PREPARE.
