TC: int findfirst( const char *path, struct ffblk *ffblk, int attr)
MSC unsigned _dos_findfirst( char *path, unsigned attr,
struct find_t *fileinfo )
- prototype in dir.h, also include dos.h (MS C: dos.h only)
- gets disk directory via DOS 0x4E, where attr is:
Turbo C Microsoft C
FA_RDONLY _A_RDONLY
FA_HIDDEN _A_HIDDEN
FA_SYSTEM _A_SYSTEM
FA_LABEL _A_VOLID
FA_DIREC _A_SUBDIR
FA_ARCH _A_ARCH
struct ffblk (Turbo C) struct find_t (MSC)
{ {
char ff_reserved[21]; char reserved[21];
char ff_attrib; char attrib;
unsigned ff_ftime; unsigned wr_time;
unsigned ff_fdate; unsigned wr_date;
long ff_fsize; long size;
char ff_name[13]; char name[13];
}; };
- attributes can be logically OR'ed
- struct ffblk is defined in Turbo C's dir.h
- struct find_t is defined in MS C's dos.h
- updates DTA, provisions for saving/setting DTA should be made
- normal files are always included along with files that match
the requested attributes except when the LABEL attribute is
requested. It's up to the programmer to determine which
actually match the requested attributes.
- returns 0 if OK, -1 if no matching files found or on error
- see FILE ATTRIBUTES, FINDNEXT, GETDTA and SETDTA
