Hello netters ... I've a question about interface between Informix 4GL and C ... I want to call 4GL functions in a C modules... my problem is the parameters !! In the manual, they explain how to pass arguments to C functions called by 4GL program .. but not in the other way .. I guess it's kind of the same way (I must use popint .. and pushint ..??) , I must use the stack, push before calling, and pop when the function return to C module ... But I need to know, for example, if I need to know the size of the char I want to get from 4GL function etc ... Thanx in advance for your help .... -- Arnaud Girsch (aka Nono) | E-Mail : Arnaud.Girsch@INSA-Lyon.FR System Admin | postmaster@aedi.INSA-Lyon.FR (Sys Admin) Computer Science Dept | irc@Univ-Lyon1.FR (IRC Admin) INSA Lyon - FRANCE | Voice : (+33) 72.43.71.77
