Here is the call graph for this function:

int db_mysql_fetch_result ( const db1_con_t *  _h,
db1_res_t **  _r,
const int  nrows 
)

fetch rows from a result

Gets a partial result set, fetch a number of rows from a database result. This function initialize the given result structure on the first run, and fetches the nrows number of rows. On subsequenting runs, it uses the existing result and fetches more rows, until it reaches the end of the result set. Because of this the result needs to be null in the first invocation of the function. If the number of wanted rows is zero, the function returns anything with a result of zero.

Parameters:
_h structure representing the database connection
_r pointer to a structure representing the result
nrows number of fetched rows
Returns:
zero on success, negative value on failure
