The function ex_put_qa() writes the QA records to the database. Each
QA record contains four \c MAX_STR_LENGTH-byte character
strings. The character strings are:

 -  the analysis code name
 -  the analysis code QA descriptor
 -  the analysis date
 -  the analysis time

\return In case of an error, ex_put_qa() returns a negative number; a
        warning will return a positive number. Possible causes of errors
        include:
  -  data file not properly opened with call to ex_create() or ex_open()
  -  data file opened for read only.
  -  QA records already exist in file.

\param[in] exoid            exodus file ID returned from a previous call to ex_create() or ex_open().

\param[in] num_qa_records   The number of QA records.
\param[in]  qa_record       Array containing the QA records.

The following code segment will write out two QA records:

\code
#include "exodusII.h"
int num_qa_rec, error, exoid;
char *qa_record[2][4];

\comment{write QA records}
num_qa_rec = 2;

qa_record[0][0] = "TESTWT1";
qa_record[0][1] = "testwt1";
qa_record[0][2] = "07/07/93";
qa_record[0][3] = "15:41:33";
qa_record[1][0] = "FASTQ";
qa_record[1][1] = "fastq";
qa_record[1][2] = "07/07/93";
qa_record[1][3] = "16:41:33";

error = ex_put_qa (exoid, num_qa_rec, qa_record);
\endcode
