Hi: I am wanting to define some functions as described in section 35.9 of the manual, "C-Language Functions." I am compiling pre-existing files of c-code from another project into object files, and then linking those object files into a shared library along with my own functions that follow the posgresql calling convention, invoking other functions as desired. This pre-existing c-code I'm compiling happens to contain a function named "point_add()". I see the postgresql source file fmgrtab.c also has a function with the same name. When my code tries to invoke its version of point_add() I get a bus error, and when I changed the name of that function to something else the bus error went away. Of course, since I'm working with source code I can just keep the modified function name, but I would like to be able to keep my version of this c code updated with that project and so to use it unmodified. So my questions are: first, might I be wrong about the cause of this bus error? I cannot think of another reason why changing the name of a function would have this effect, but maybe there's some other reason besides the "point_add()" function in fmgrtab.c conflicting. If so, I'm interested to know. If, however, it is probable that this bus error is a result of this naming conflict, then do I have any options for working around it that would enable me to use the code from this other library without changing the name of its "point_add()" function? I know I could ask that project's developers to change the function's name, but that could break other code that currently uses it, and even if it didn't, I would prefer something less intrusive on that project. Thanks very much for any ideas about this, -- Adam Mackler -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
