SQLITE3_LOG(3)          NetBSD Library Functions Manual         SQLITE3_LOG(3)


NAME

     sqlite3_log -- error logging interface


SYNOPSIS

     #include <sqlite3.h>

     void
     sqlite3_log(int iErrCode, const char *zFormat, ...);


DESCRIPTION

     The sqlite3_log() interface writes a message into the error log estab-
     lished by the SQLITE_CONFIG_LOG option to sqlite3_config().  If logging
     is enabled, the zFormat string and subsequent arguments are used with
     sqlite3_snprintf() to generate the final output string.

     The sqlite3_log() interface is intended for use by extensions such as
     virtual tables, collating functions, and SQL functions.  While there is
     nothing to prevent an application from calling sqlite3_log(), doing so is
     considered bad form.

     The zFormat string must not be NULL.

     To avoid deadlocks and other threading problems, the sqlite3_log() rou-
     tine will not use dynamically allocated memory.  The log message is
     stored in a fixed-length buffer on the stack.  If the log message is
     longer than a few hundred characters, it will be truncated to the length
     of the buffer.


IMPLEMENTATION NOTES

     These declarations were extracted from the interface documentation at
     line 9932.
