*template);
openpam_subst
() function expands a string,
substituting PAM item values for all occurrences of specific substitution
codes. The template argument points to the initial
string. The result is stored in the buffer pointed to by the
buf argument; the bufsize argument
specifies the size of that buffer. The actual size of the resulting string,
including the terminating NUL character, is stored in the location pointed to
by the bufsize argument.
If buf is NULL, or if the buffer is too
small to hold the expanded string, bufsize is updated
to reflect the amount of space required to hold the entire string, and
openpam_subst
() returns
PAM_TRY_AGAIN
.
If openpam_subst
() fails for any other
reason, the bufsize argument is untouched, but part of
the buffer may still have been overwritten.
Substitution codes are introduced by a percent character and correspond to PAM items:
PAM_RHOST
item.PAM_HOST
item.PAM_SERVICE
item.PAM_TTY
item.PAM_RUSER
item.PAM_USER
item.openpam_subst
() function returns one of the
following values:
PAM_SUCCESS
]PAM_BAD_ITEM
]PAM_TRY_AGAIN
]openpam_subst
() function is an OpenPAM extension.
