- On IRIX systems, this routine is in lliibbffoorrttrraann..ssoo which is linked by
- default when compiling programs with the MIPSpro 7 Fortran 90 compiler
- or when compiling programs with the --ccrraayylliibbss option to the MIPSpro
- F77 compiler.
-
- The PPXXFFCCHHRROOOOTT subroutine uses the cchhrroooott(2) system call to change the
- root directory to the specified directory.
-
- When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
- UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
- kind unless documented otherwise. On UNICOS and UNICOS/mk, default
- kind is KKIINNDD==88 for integer, real, complex, and logical arguments; on
- IRIX, the default kind is KKIINNDD==44.
-
- The following is a list of valid arguments for this subroutine:
-
- _p_a_t_h Input character variable or array element containing the
- name of a file.
-
- _i_l_e_n Input integer variable containing the length of _p_a_t_h in
- characters. If _i_l_e_n is zero, all trailing blanks are
- removed before calling cchhrroooott().
-
- _i_e_r_r_o_r Output integer variable that contains zero if the root
- directory was changed to the directory specified by _p_a_t_h or
- nonzero if the root directory was not changed.
-
- In addition to the errors returned by the cchhrroooott(2) system call,
- PPXXFFCCHHRROOOOTT may return the following errors:
-
- EEIINNVVAALL If _i_l_e_n is less than 0 or if _i_l_e_n is greater than LLEENN((_p_a_t_h))
-
- EENNOOMMEEMM If PPXXFFCCHHRROOOOTT is unable to obtain memory to copy _p_a_t_h
