reqpar_processor2 - process parameter file and request parameter values
from database
reqpar_processor2 reads from a file descriptor
to obtain strins containing label/refname pairs. Each time the function
is called one string file is read and parsed and a parameter value request
is formulated and sent to
dbman.
The application using this function may
define a list of keywords. When reqpar_processor2 sees one of the keywords
it calls a callback function to process it.
The file should be opened before
calling this function and closed when finished.
This function is part of
librmt.
int reqpar_processor2(
FILE *in,
int DBsock,
int *Line,
char *tlist[],
int tlist_cnt,
int (*tlist_callback)(
char *token[],
int tcnt,
int Line,
char *terminator
),
char *terminator,
int verbosity
);
The pathname of the file to read from.
The file descriptor
for the connection to dbman.
a variable containing the current line
number of the file being processed. This should be initialized to zero before
calling this function the first time.
This is more or less useless since
this function usually won’t be reading from a file.
A list of keyword
strings. When a match is found in this list tlist_callback() is called to
process the line.
The number of items in the tlist array.
This
function is called when a match is found in the tlist.
- token
The input string is broken into tokens. This is the token array. - tcnt
The number of tokens in the token array. - Line
The line number. This is more or less useless since this function usually
won’t be reading from a file. - terminator
The terminator parameter from the function call is passed here. The callback
should be written to behave in the same way as the function.
A pointer to a string to use as a line terminator. If the pointer is NULL
a LF is used as the terminator, otherwise the contents of the string is
used as the terminator.
Defines the amount of messages to print.
This value is passed on to SendRec. A value of 0 produces no messages. See
the SendRec manpage for full details on available values.
-1
- error, end of input, bad db connection
0 - no record processed
comment and empty lines return this
1 - record processed
This function was written for use with
inet_reqpar(1)
. One has to wonder
if it’s too specialized to be in the library. 12-7-04rlk
