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. * * int irp_unmarshall_XX(struct YYYYY *XX, char *buffer); * * The unmashalling functions break apart the buffer and store the * values in the struct pointed to by XX. All pointer values inside * XX are allocated with malloc. All arrays of pointers have a NULL * as the last element. */ #endif
