This section describes C API functions other than those used for prepared statements. For information about those, seeSection 6.4, “C API Prepared Statement Function Descriptions”.
In the descriptions here, a parameter or return value ofNULL meansNULL in the sense of the C programming language, not a MySQLNULL value.
Functions that return a value generally return a pointer or an integer. Unless specified otherwise, functions returning a pointer return a non-NULL value to indicate success or aNULL value to indicate an error, and functions returning an integer return zero to indicate success or nonzero to indicate an error. Note that“nonzero” means just that. Unless the function description says otherwise, do not test against a value other than zero:
if (result) /* correct */ ... error ...if (result < 0) /* incorrect */ ... error ...if (result == -1) /* incorrect */ ... error ... When a function returns an error, theErrors subsection of the function description lists the possible types of errors. You can find out which of these occurred by callingmysql_errno(). A string representation of the error may be obtained by callingmysql_error().
