t_csvrd_err csvrd	(	const t_filename *	aFileName,
		const char *	fldseps,
		const char *	recseps,
		const char *	ignchars,
		t_cbfld	aCbFld,
		t_cbrec	aCbRec,

	)

Parses CSV files.

Example for parsing a comma separated file with CR-LF on line ends:

 #include <stdio.h>
 #include "csvrd.h"
 
 static const char *FLDSEPS = ",";
 static const char *RECSEPS = "\n";
 static const char *CH2IGNORE = "\r";
 
 static short _cbfld(const char *fld, int fldno, short perc, void *ctx) {
   printf("fld[%d]=%s ", fldno, fld);
   return 1;
 }
 
 static short _cbrec(int recno, short perc, void *ctx) {
   printf("rec[%d] finished\n", recno);
   return 1;
 }
 
 int main(int argc, char **argv) {
   int i, retval;
 
   retval = CSVRD_OK;
   for(i = 1; i < argc; i++) {
     retval = (int) csvrd(argv[i],
                          FLDSEPS, 
                          RECSEPS,
                          CH2IGNORE,
                          _cbfld,
                          _cbrec,
                          NULL);
     if (retval != CSVRD_OK) break;
   }
   return retval;
 }

Parameters:

	aFileName	name of the CSV file to parse.
	fldseps	field separators, set of characters as 0 terminated string. Usually something like ",", ",;" etc. Must not be NULL.
	recseps	record separators, set of characters as 0 terminated string. Example "\n". Must not be NULL.
	ignchars	characters to ignore while reading the CSV file. Example "\r". Must not be NULL, pass an empty string if you don't want to ignore characters.
	aCbFld	callback function for each parsed field. May be NULL.
	aCbRec	callback function called after each parsed record.
	ctx	context for callback functions.

Returns:

CSVRD_OK or error code.
