A C program required for portability
I have to solve a problem for my wife who is engaged in Research in Breast Cancer.
1. She has frequently to search a long single line of alphabetic characters (lower case) for an exact match of a string.
e.g. mwaaagglwrsraglralfrsrdaalfpgcerglhcsavscknwlkkfasktkkkvwyespslgshstykpskleflmrstskktrkedharlralngll ykaltdllctpevsqelydlnvelskvsltpdfsacraywkttlsaeqnahmeavlqrsaahmslisywqsqtldpgmkettlykmisgtlmphnpaapq srpqapvcvgsimrrstsrlwstkggkikgsgawcgrgrwls
2. The ONLY two strings to be searched for are -
r-r--s
r-r--t
The - can be any of the following characters
acdefghiklmnpqrstvxy
3. Once an exact match/s has been made it is essential to know the number of characters from the start of the line inclusive of the 6 character string to each match.
Can anyone suggest a program in ANSI C that will compile in the first instance in Solaris (SunOS 5.9).
But is portable (source and then re compile) to HP-UX and AIX and to XP.
It is urgent.
Thanks
Nev
p.s. The immediate need has been solved with a ksh script but c is necessary to match some other utilities.
Also we have to solve a problem in that the raw data although shown as one line above; comes as many lines sometimes as many as 50 so we have to join these lines to make one single line. It does not alter the data at all as it is shown as many lines only on for ease of display purposes.

ldapfilter.conf
ldapfilter.conf(4) File Formats ldapfilter.conf(4)
NAME
ldapfilter.conf - configuration file for LDAP filtering routines
SYNOPSIS
/etc/opt/SUNWconn/ldap/current/ldapfilter.conf
DESCRIPTION
The ldapfilter.conf file contains information used by the LDAP filtering routines.
Blank lines and lines that begin with a hash character (#) are treated as comments and ignored. The configuration information consists of
lines that contain one to five tokens. Tokens are separated by white space, and double quotes can be used to include white space inside a
token.
The file consists of a sequence of one or more filter sets. A filter set begins with a line containing a single token called a tag.
The filter set consists of a sequence of one or more filter lists. The first line in a filter list must contain four or five tokens: the
value pattern, the delimiter list, a filtertemplate, a match description, and an optional search scope. The value pattern is a regular
expression that is matched against the value passed to the LDAP library call to select the filter list.
The delimiter list is a list of the characters (in the form of a single string) that can be used to break the value into distinct words.
The filter template is used to construct an LDAP filter (see description below)
The match description is returned to the caller along with a filter as a piece of text that can be used to describe the sort of LDAP search
that took place. It should correctly compete both of the following phrases: "One match description match was found for ..." and "Three
match description matches were found for...."
The search scope is optional, and should be one of base, onelevel, or subtree. If search scope is not provided, the default is subtree.
The remaining lines of the filter list should contain two or three tokens, a filter template, a match description and an optional search
scope.
The filter template is similar in concept to a printf(3C) style format string. Everything is taken literally except for the character
sequences:
%v Substitute the entire value string in place of the %v.
%v$ Substitute the last word in this field.
%vN Substitute word N in this field (where N is a single digit 1-9). Words are numbered from left to right within the value starting
at 1.
%vM-N Substitute the indicated sequence of words where M and N are both single digits 1-9.
%vN- Substitute word N through the last word in value where N is again a single digit 1-9.
EXAMPLES
Example 1 An LDAP Filter Configuration File
The following LDAP filter configuration file contains two filter sets, example1 and example2 onelevel, each of which contains four filter
lists.
# ldap filter file

"[0-9][0-9-]*" " " "(telephoneNumber=*%v)" "phone number"
