November 14, 2001 dos.h _dos_findfirst example | ||||

| ||||
Hello, I'm evaluating the DM C compiler for use in porting old MS DOS C v6.0 code. When I try to compile/ling the example code from the dos.h _dos_findfirst example I get: d:\c60\test>sc ffirst.c link ffirst,,,user32+kernel32/noi; OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved ffirst.obj(ffirst) Error 42: Symbol Undefined __dos_findfirst ffirst.obj(ffirst) Error 42: Symbol Undefined __dos_findnext --- errorlevel 2 Does anyone have any suggestions as to what I might be doing wrong? Thanks for any help. Here's the example code: /* Example for _dos_findfirst and _dos_findnext */ #include <dos.h> #include <stdio.h> #include <stdlib.h> void list_name( struct find_t fileinfo) { int result; result = _dos_findnext (& fileinfo); if (result == 0) { printf ("% s\n", fileinfo. name); list_name (fileinfo); } else printf ("List done\n"); } void main() { int result; struct find_t ffblk; result = _dos_findfirst ("*.dat", _A_NORMAL, &ffblk); if (result == 0) { printf ("% s\n", ffblk. name); list_name (ffblk); } else printf ("No files match *.dat\n"); } |

Posted in reply to Victor P. Dura | You will have to compile with
sc -ml ffirst.c
Or other compiler flags that generate a DOS executable.
sc now by default generates a Win32 executable. Win32 does not have
_dos_findfirst or _dos_findnext.
