10.5.2.17 ChDir Intrinsic (function)

 
ChDir(Dir)

ChDir: INTEGER(KIND=1) function.

Dir: CHARACTER; scalar; INTENT(IN).

Intrinsic groups: badu77.

Description:

Sets the current working directory to be Dir. Returns 0 on success or a non-zero error code. See chdir(3).

Caution: Using this routine during I/O to a unit connected with a non-absolute file name can cause subsequent I/O on such a unit to fail because the I/O library might reopen files by name.

Due to the side effects performed by this intrinsic, the function form is not recommended.

For information on other intrinsics with the same name: See section 8.11.9.40 ChDir Intrinsic (subroutine).
