SUMMARY forfile

#include <tools.h>

int forfile(pstrPattern, attr, pProc, args)
char *pstrPattern;      /* search pattern */
int attr;               /* file attributes to match */
void (*pProc)();        /* proc called for each file found */
unsigned args;          /* extra args for call back proc */

Proc(pstrName, pFindBuf, pArgs)  /* routine called for each enumerated file */
char *pstrName;
struct findType *pFindBuf;
unsigned *pArgs;

DESCRIPTION

For all files matching with a file name matching pstrPattern and having
a subset of the attributes attr, the routine pProc is called and passed
the a completed pattern for the file, a pointer to the find buffer for
the file and a pointer to args.

RETURN VALUE

Control is returned from forfile after all files, if any, have been
enumerated and pProc called for each.  forfile returns FALSE if no files
were enumerated and returns TRUE if one or more were enumerated.

IMPLEMENTATION

char *pstrBuf = alloc buffer size MAXPATHLEN;
char *p;
struct findType *pFindBuf;

drive(pstrPattern, pstrBuf);        /* copy drive part of pattern */
path(pstrPattern, strend(pstrBuf);  /* copy path  part of pattern */
p = strend(pstrBuf);                /* remember end of current pattern */

do {
    strcpy(p, pFindBuf->name);  /* add on completed file name */
    lower(p);
    (*pProc)(pstrBuf, pFindBuf, pArgs);
    } while (fnext(fFindBuf));

NOTE

Patterns and attributes are described separately.

EXAMPLE

#include <tools.h>

DoPrint(pstrName, pFindBuf, pArgs)
char *pstrName;
struct findType *pFindBuf;
unsigned *pArgs;
{
    printf("File found %s\n", pstrName);
}

main(c, argv)
int c;
char *argv[];
{
    /* print names of C files in current directory w/ archive bit set */
    if (!forfile("*.c", A_A, DoPrint))
        printf("No files found\n");
}
