I'm not seeing that. I would be happy if you are right but I can't confirm it. I run acid on the binary: recv 0x000cd7b6 SUBL $0x10,SP recv+0x3 0x000cd7b9 MOVL flags+0xc(FP),AX recv+0x7 0x000cd7bd ANDL $0x1,AX recv+0xa 0x000cd7c0 CMPL AX,$0x0 recv+0xd 0x000cd7c3 JEQ recv+0x22(SB) recv+0xf 0x000cd7c5 MOVL $0x29,errno(SB) recv+0x19 0x000cd7cf MOVL $0xffffffff,AX recv+0x1e 0x000cd7d4 ADDL $0x10,SP recv+0x21 0x000cd7d7 RET recv+0x22 0x000cd7d8 MOVL fd+0x0(FP),CX recv+0x26 0x000cd7dc MOVL CX,0x0(SP) recv+0x29 0x000cd7df MOVL a+0x4(FP),CX recv+0x2d 0x000cd7e3 MOVL CX,0x4(SP) recv+0x31 0x000cd7e7 MOVL n+0x8(FP),CX recv+0x35 0x000cd7eb MOVL CX,0x8(SP) recv+0x39 0x000cd7ef CALL read(SB) recv+0x3e 0x000cd7f4 ADDL $0x10,SP recv+0x41 0x000cd7f7 RET so it calls read.

There is only one read symbol in the binary, and it's a T. So I am not convinced the recv is calling the wrong thing. That said, I'm still going to change it in source to see what happens :-) ron
