SUMMARY curdir

#include <tools.h>

int curdir(pstrBuf, chDrive)
char *pstrBuf;
char chDrive;

DESCRIPTION

curdir constructs a string at pstrBuf that is the current directory of the
specified drive.  If chDrive is zero, then the current drive is used.
pstrBuf is assumed to be large enough to hold the path, e.g. MAXPATHLEN from
tools.h.

RETURN VALUE

Returns non-zero if invalid drive else zero.

IMPLEMENTATION

Uses dos function 19h if no drive specified and 47h to get current directory.

SEE ALSO   rootpath

NOTE


EXAMPLE

#include <tools.h>

main(c, argv)
int c;
char *argv[];
{
    char str[MAXPATHLEN];

    curdir(str, 0); printf("current directory %s\n", str);
}
