The mask is the set of bits which may be on and the file still be returned. You _always_ get files with no bits on... BTW for TC/BC the function is just called findfirst(), I believe. Here's some example code ... this makes a cheap version of the Unix rm program, complete with recursive delete. Coded for BC++ 2.0 or higher (but should work on TC++ as well). Hope this shines some light on your problem. #define MAKE_RM_EXE 1 #if MAKE_RM_EXE #include <stdio.h> #include <stdlib.h> static int verbose = 0; static int recurse = 0; #define VPrintf if (verbose) printf #endif #include <string.h> #include <dos.h> #include <dir.h> static void makefullpath(char *path, char *name, char *fullpath) { char dsk[ MAXDRIVE ]; char dir[ MAXDIR ]; char file[ MAXFILE ]; char ext[ MAXEXT ]; char newfile[ MAXFILE ]; char newext[ MAXEXT ]; fnsplit(path, dsk, dir, file, ext); fnsplit(name, NULL, NULL, newfile, newext); fnmerge(fullpath, dsk, dir, newfile, newext); } int NukeFiles(char *path, int recurse) { int cnt=0; struct ffblk ffb; if (!findfirst(path, &ffb, -1)) { do { char fullpath[ MAXPATH ]; if (!strcmp(ffb.ff_name, ".") || !strcmp(ffb.ff_name, "..")) continue; makefullpath(path, ffb.ff_name, fullpath); if (ffb.ff_attrib & FA_DIREC) { if (recurse) { char newpath[ MAXPATH ]; strcpy(newpath, fullpath); strcat(newpath, "\\*.*"); #if MAKE_RM_EXE VPrintf("recursing to delete %s\n", newpath); #endif cnt += NukeFiles(newpath,1); #if MAKE_RM_EXE VPrintf("removing directory %s\n", fullpath); #endif rmdir(fullpath); } } else { #if MAKE_RM_EXE VPrintf("deleting %s\n", fullpath); #endif unlink(fullpath); cnt++; } } while (!findnext(&ffb)); } return cnt; } #if MAKE_RM_EXE static void options(char *opts) { while (*++opts) { switch (opts[ 0 ]) { case 'r': case 'R': recurse = 1; break; case 'v': case 'V': verbose = 1; break; default: fprintf(stderr, "nuke: unknown option '%c'\n", opts[ 0 ]); break; } } } int main(int ac, char **av) { int cnt=0; if (ac > 1 && av[1][0] == '-' || av[1][0] == '/') { options(*++av); --ac; } if (ac == 1) { fprintf(stderr, "usage: nuke [-rRvV] path ...\n"); return 1; } while (--ac > 0) cnt += NukeFiles(*++av,recurse); VPrintf("Nuked %d files!\n", cnt); return 0; } #endif Alan -- Internet: aeldridge@p473.f150.n3603.z1.FIDONET.ORG UUCP: ...!myrddin!tct!psycho!150.473!aeldridge Note:psycho is a free gateway between Usenet & Fidonet.
