Informix / C parameter passing

My thanks to Jonathan Leffler, for his comments about parameter passing. It appears to me that this is EXTREMELY 4gl-version dependent. Once again, here is the 4GL for my empty function, followed by the C generated by the version 2.10 compiler. empty.4gl --------- FUNCTION empty ( a, b, c ) DEFINE a, b CHAR(256), c CHAR(512), d CHAR(512) RETURN d empty.c (produced by version 2.10 c4gl) ------- #include <sqlhdr.h> #include <sqlfm.h> #line 1 "empty.ec" #include <decimal.h> #include <stdio.h> extern struct { long sqlcode; char sqlerrm[ 72 ]; char sqlerrp[ 8 ]; long sqlerrd[ 6 ]; char sqlawarn[ 8 ]; } sqlca; #line 8 "empty.ec" extern int status; #line 9 "empty.ec" extern int efcode; extern int int_flag; #line 11 "empty.ec" extern int quit_flag; #line 12 "empty.ec" static char *fgl_modname = "empty.4gl"; empty (fgl_pcnt) int fgl_pcnt; { #line 17 "empty.ec" char a[ 257 ], b[ 257 ]; #line 18 "empty.ec" char c[ 513 ]; #line 19 "empty.ec" char d[ 513 ]; #line 20 "empty.ec" if (fgl_pcnt != 3) fgl_fatal(fgl_modname, 6, -4501); popquote(c,513); popquote(b,257); popquote(a,257); pushquote(d,512); doretalloc(1); return(1); } #line 28 "empty.ec" Perhaps in version 2.10 the 'doretalloc' call served the 'retquote' purpose. I don't know: It's your (Informix's) code generator. I chose not to use it, and the function still works. I stand by my statement to compile empty.4gl and then modify my function to use the same sort of calling and return sequences that you find in the resulting empty.c.
