Module Name:
ws2hdr.c
Abstract:
Munges the WinSock 2.0 header file.
This program scans stdin, searching for begin and end tags. Lines of
text between these tags are assumed to be function prototypes of the
form:
function_linkage
return_type
calling_convention
function_name(
parameters,
parameters,
...
);
For each such function prototype found, the following is output:
#if INCL_WINSOCK_API_PROTOTYPES
function_linkage
return_type
calling_convention
function_name(
parameters,
parameters,
...
);
#endif
#if INCL_WINSOCK_API_TYPEDEFS
typedef
return_type
(calling_convention * LPFN_FUNCTION_NAME)(
parameters,
parameters,
...
);
#endif
