AC_FUNC_ACCEPT_ARGTYPES
1.1.1.1 (2001/07/26) Miscellaneous @ ac-archive-0.5.39
Daniel Richard G. <skunk@mit.edu>
Checks the data types of the three arguments to accept(). Results are placed into the symbols ACCEPT_TYPE_ARG[123], consistent with the following example:
#define ACCEPT_TYPE_ARG1 int
#define ACCEPT_TYPE_ARG2 struct sockaddr *
#define ACCEPT_TYPE_ARG3 socklen_t *
This macro requires AC_CHECK_HEADERS to have already verified the presence or absence of sys/types.h and sys/socket.h.
NOTE: This is just a modified version of the AC_FUNC_SELECT_ARGTYPES macro. Credit for that one goes to David MacKenzie et. al.
