/*
|
|
* Functions to marshall and unmarshall various system data structures. We
|
|
* use a printable ascii format that is as close to various system config
|
|
* files as reasonable (e.g. /etc/passwd format).
|
|
*
|
|
* We are not forgiving with unmarhsalling misformatted buffers. In
|
|
* particular whitespace in fields is not ignored. So a formatted password
|
|
* entry "brister :1364:100:...." will yield a username of "brister "
|
|
*
|
|
* We potentially do a lot of mallocs to fill fields that are of type
|
|
* (char **) like a hostent h_addr field. Building (for example) the
|
|
* h_addr field and its associated addresses all in one buffer is
|
|
* certainly possible, but not done here.
|
|
*
|
|
* The following description is true for all the marshalling functions:

/* int irp_marshall_XX(struct yyyy *XX, char **buffer, size_t *len);
|
|
*
|
|
* The argument XX (of type struct passwd for example) is marshalled in the
|
|
* buffer pointed at by *BUFFER, which is of length *LEN. Returns 0
|
|
* on success and -1 on failure. Failure will occur if *LEN is
|
|
* smaller than needed.
|
|
*
|
|
* If BUFFER is NULL, then *LEN is set to the size of the buffer
|
|
* needed to marshall the data and no marshalling is actually done.
|
|
*
|
|
* If *BUFFER is NULL, then a buffer large enough will be allocated
|
|
* with memget() and the size allocated will be stored in *LEN. An extra 2
|
|
* bytes will be allocated for the client to append CRLF if wanted. The
|
|
* value of *LEN will include these two bytes.
|
|
*
|
|
* All the marshalling functions produce a buffer with the fields
|
|
* separated by colons (except for the hostent marshalling, which uses '@'
|
|
* to separate fields). Fields that have multiple subfields (like the
|
|
* gr_mem field in struct group) have their subparts separated by
|
|
* commas.
