I don't appear to be having any luck using the n_setttexisparam API followed by n_texis to execute the query.
This code fragment:
if (!n_settexisparam(se,1,"KR",(int *)NULL,SQL_C_CHAR,SQL_LONGVARCHAR)) {
printf("setparam failed\n");
} else if(!n_texis(se, "select id from patent where length(pabstract)=?;", sql)) {
FREE_CONFIG();
printf("%s\n", errorString);
}

Produces this result:
SQL: Needed parameters not supplied in the function: execntexis

Would I encounter the same problem using n_preptx and n_exectx?

I notice in this example the programmer was able to get an error text message using "errorString" which appears to be something he defined in his program. How do I get the error text from an unsuccessful call to n_texis?

API errors are reported through the putmsg() function. acoulson0 is probably setting a global within a customized putmsg() function. See putmsg replacement in the manual
