netcdf – Unidata Network Common Data Form (netCDF-2) library Warning The interface described here is obsolete, but included because the perl module still use it. Synopsis #include <netcdf.h> int nccreate(const char* path, int cmode) int ncopen(const char* path, int mode) int ncredef(int ncid) int ncsetfill(int ncid, int fillmode) int ncendef(int ncid) int ncclose(int ncid) int…

nerr_register Synopsis #include <util/neo_err.h> NEOERR *nerr_register (NERR_TYPE *err, const char *name); Arguments err – pointer to a NERR_TYPE name – pretty name for the error type Description register an error type. This will assign a numeric value to the type, and keep track of the "pretty name" for it. See Also nerr_error_traceback(3), nerr_pass(3), nerr_error_string(3), defined(3),…

nerr_pass_ctx Synopsis #include <util/neo_err.h> nerr_pass_ctx() Arguments with the macro, the function name, file and lineno are automagically recorded. Just pass the error and a printf format string giving more information about where the error is occuring. Description this function is used to pass an error up a level in the call chain (ie, if the…

nerr_pass Synopsis #include <util/neo_err.h> nerr_pass() Arguments with the macro, the function name, file and lineno are automagically recorded. Just pass the error. Description this function is used to pass an error up a level in the call chain (ie, if the error isn’t handled at the current level). This allows us to track the traceback…

nerr_match Synopsis #include <util/neo_err.h> int nerr_match(NEOERR *err, NERR_TYPE type); Arguments err – the NEOERR that has an error. type – the NEOERR type, as registered with nerr_register Description nerr_match is used to walk the NEOERR chain and match the error against a specific error type. In exception parlance, this would be the equivalent of "catch"….

nerr_log_error Synopsis #include <util/neo_err.h> void nerr_log_error(NEOERR *err); Description currently, this prints out the error to stderr, and free’s the error chain See Also nerr_error_traceback(3), nerr_pass(3), nerr_error_string(3), defined(3), nerr_pass_ctx(3), nerr_passf(3), nerr_init(3), nerr_match(3), nerr_log_error(3), nerr_ignore(3), nerr_register(3), nerr_handle

nerr_init Synopsis #include <util/neo_err.h> NEOERR *nerr_init (void); Arguments None Description initialize the NEOERR system. Can be called more than once. Is not thread safe. This registers all of the built in error types as defined at the top of this file. If you don’t call this, all exceptions will be returned as UnknownError. See Also…

nerr_ignore Synopsis #include <util/neo_err.h> void nerr_ignore(NEOERR **err); Description you should only call this if you actually handle the error (should I rename it?). Free’s the error chain. See Also nerr_error_traceback(3), nerr_pass(3), nerr_error_string(3), defined(3), nerr_pass_ctx(3), nerr_passf(3), nerr_init(3), nerr_match(3), nerr_log_error(3), nerr_ignore(3), nerr_register(3), nerr_handle

nerr_handle Synopsis #include <util/neo_err.h> int nerr_handle(NEOERR **err, NERR_TYPE type); Arguments err – pointer to a pointer NEOERR type – the NEOERR type, as registered with nerr_register Description nerr_handle is a convenience function. It is the equivalent of nerr_match, but it will also deallocate the error chain on a match. See Also nerr_error_traceback(3), nerr_pass(3), nerr_error_string(3), defined(3),…

nerr_error_traceback Synopsis #include <util/neo_err.h> void nerr_error_traceback(NEOERR *err, STRING *str); Arguments err – error str – string to which the data is appended Description returns the full traceback of the error chain See Also nerr_error_traceback(3), nerr_pass(3), nerr_error_string(3), defined(3), nerr_pass_ctx(3), nerr_passf(3), nerr_init(3), nerr_match(3), nerr_log_error(3), nerr_ignore(3), nerr_register(3), nerr_handle

nerr_error_string Synopsis #include <util/neo_err.h> void nerr_error_string(NEOERR *err, STRING *str); Arguments err – error str – string to which the data is appended Description returns the string associated with an error (the bottom level of the error chain) See Also nerr_error_traceback(3), nerr_pass(3), nerr_error_string(3), defined(3), nerr_pass_ctx(3), nerr_passf(3), nerr_init(3), nerr_match(3), nerr_log_error(3), nerr_ignore(3), nerr_register(3), nerr_handle

neon – HTTP and WebDAV client library Description neon is an HTTP and WebDAV client library. The major abstractions exposed are the HTTP session, created by ne_session_create; and the HTTP request, created by ne_request_create. HTTP authentication is handled transparently for server and proxy servers, see ne_set_server_auth; complete SSL/TLS support is also included, see ne_ssl_set_verify. Conventions…

need_uconvert – Tells if a string requires encoding conversion. Allegro game programming library. Synopsis #include <allegro.h> int need_uconvert(const char *s, int type, int newtype); Description Given a pointer to a string (`s’), a description of the type of the string (`type’), and the type that you would like this string to be converted into (`newtype’),…
