# This awk script parses C input files looking for lines marked "PUBLIC:"
|
|
# and "EXTERN:". (PUBLIC lines are DB internal function prototypes and
|
|
# #defines, EXTERN are DB external function prototypes and #defines.)
|
|
#
|
|
# PUBLIC lines are put into two versions of per-directory include files:
|
|
# one file that contains the prototypes, and one file that contains a
|
|
# #define for the name to be processed during configuration when creating
|
|
# unique names for every global symbol in the DB library.
|
|
#
|
|
# The EXTERN lines are put into two files: one of which contains prototypes
|
|
# which are always appended to the db.h file, and one of which contains a
|
|
# #define list for use when creating unique symbol names.
|
|
#
|
|
# Four arguments:
|
|
# e_dfile list of EXTERN #defines
|
|
# e_pfile include file that contains EXTERN prototypes
|
|
# i_dfile list of internal (PUBLIC) #defines
|
|
# i_pfile include file that contains internal (PUBLIC) prototypes
|
