44 * This function searches for "srch_str" (of length "slen") in "buf" (of length
45 * "buflen"). If it is not found, "write_offset" has the offset in "buf" where
46 * "srch_str" would have to be added in "buf". If "srch_str" is found in "buf",
47 * "write_offset" has its offset in "buf"
48 *
49 * ARGUMENTS :
50 * buf - buffer to search in
51 * buflen - length of buffer
52 * srch_str - string to search
53 * slen - length of srch_str
54 * write_offset - Set in function on exit
55 * - It is the offset in buf where srch_str is or should be
56 * bytes_left - Set in function on exit
57 * - It is the # of bytes left beyond write_offset in buf
58 *
59 * Notes :
60 * - This function assumes "buf" is sorted in ascending order
61 * - If 'buflen' is > 0, it assumes it has a header on top and skips it
62 * - "srch_str" has '\n' at the end, but when update_fabric_wwn_list() calls
63 * this function, 'slen' does not include the last `\n'
64 *
65 * RETURN VALUES :
66 * Zero - "srch_str" found in "buf"... "write_offset" has offset in "buf"
67 * > 0 - "srch_str" NOT found in "buf" ... "write_offset" has offset in "buf"
68 * where "srch_str" can fit in.
69 * "buf" had contents > "srch_str"
70 * < 0 - "srch_str" NOT found in "buf" ... "write_offset" has offset in "buf"
71 * where "srch_str" can fit in.

188 * INPUTS:
189 * cmd - ADD_ENTRY or REMOVE_ENTRY
190 * update_str - string for repository operation
191 * - Assumed NOT to have a '\n' and that it is null terminated
192 * errstring - Pointer that will be updated by this function
193 * - Any error msgs that has to be sent back to caller
194 *
195 * RETURNS :
196 * FPCFGA_OK on success
197 * FPCFGA_LIB_ERR on error
198 *
199 * SYNOPSIS:
200 * This function adds or deletes 'update_str' from FAB_REPOSITORY based on
201 * value of 'cmd'. The repository has a warning line on the top to disallow
202 * manual editing of the file. If the repository is being created fresh or if
203 * it is of zero length or if it has only warning lines in it, the operation
204 * speicified by 'cmd' is performed and returned. If the repository exists
205 * and has some data, it is expected to be of atleast the size of the lenght
206 * of the warning header. This is the only check that is performed on the
207 * validity of the file. No other checks are performed. On a valid
208 * repository, to perform the update, this function basically makes use of
209 * 3 buffers - the original buffer (repbuf), a copy buffer (c_repbuf) and a
210 * temp buffer (t_repbuf).
211 * The contents of the repository are mmap-ed into the repbuf and then
212 * copied into the c_repbuf. All further operations are done using the copy.
213 * t_repbuf is created to be the size of c_repbuf +/- 'slen' (based on
214 * whether it is add or remove operation). After adding/removing the
215 * 'update_str', the c_repbuf is copied to a OLD_FAB_REPOSITORY and t_repbuf
216 * is made FAB_REPOSITORY.
