Multi-Thread on ESQL/C 7.24UC7

Hi all I have a question hwo to make my program with "Multi-Thread" by using ESQL/C 7.24UC7. The attached files are "DB.ec", "current.ec", "version.txt", and "error.txt". DB.ec contains functions about db connection. current.ec contails functions about main and child threads. version.txt indicates Informix Dynamic Server and ESQL/C version information. and error.txt shows error messages when i compile DB.ec and current.ec with esql/c I had use INFORMIXC=cc. I don't know what's the problem and what shall i do for it. -- ------------- Yeonjung, Kim begin 666 DB.ec M(VEN8VQU9&4@/'-T9&EO+F@^#0HC:6YC;'5D92 \\;6%T:"YH/@T*#0HC:69N M9&5F($1%1D%53%1-14T-"B-D969I;F4@1$5&055,5$U%32 @,3 P, T*(V1E M9FEN92!44E5%(" Q#0HC9&5F:6YE($9!3%-%(# -"B-E;F1I9@T*#0IE>'1E M<FX):6YT"6QO9V9P.PT*8VAA<@EM97-S86=E6T1%1D%53%1-14U=.PT*#0I% M6$5#"5-13 E"14=)3@E$14-,05)%"5-%0U1)3TX[#0IC:&%R"6-O;C%;72 ] M(")Y<B([#0I%6$5#("!344P@14Y$($1%0TQ!4D4@4T5#5$E/3CL-"@T*:6YT M"41"7T-O;FYE8W0H*0T*>PT*"45814,)4U%,"4)%1TE."41%0TQ!4D4)4T5# M5$E/3CL-"@EC:&%R"75I9%LR,%T[#0H)8VAA<@EP87-S=V1;,C!=.PT*"458 M14,)4U%,"45.1 E$14-,05)%"5-%0U1)3TX[#0H-"@ES<')I;G1F*'5I9"P@ M(FEN9F]R;6EX(BD[#0H)<W!R:6YT9BAP87-S=V0L(")I;F9O<FUI>"(I.PT* M#0H@(" @(" @($5814,@(" @4U%,(" @("!#;VYN96-T('1O("=D<F5A;31 M9VES)R!A<R G>7(G('5S97(@.G5I9"!U<VEN9R Z<&%S<W=D(%=)5$@@0T].
