The macros offered by the LOG-package expect printf-compatible format strings with any number of arguments.
#include <l4/log/l4log.h>
- LOG(format...)
- output the log-tag followed by the formatted message.
- LOGl(format...)
- output the log-tag, the source-code file, the line number, the function number and the formatted message.
- LOGL(format...)
- output the log-tag, the source-code file, the line number, the function name, the thread-id and the message.
- LOGI(format...)
- output the log-tag, some other information, and the formatted message.
- LOG_Enter(format...)
- output the function name followed by "() called" and the formatted message. This macro should be placed in the beginning of a function to indicate the function call.
- LOG_Error(format...)
- output "Error: " and the formatted message.
The macros LOG, LOGl, LOGL and LOG_Enter come in a second flavor, with a condition variable as the first argument. They are called LOGd, LOGdl, LOGdL and LOGd_Enter. Use a condition-expression as first argument to the LOGd...-macros. The logging will occur if the expression evaluates to true. If the condition-expression is constant and false, the whole Log-Statement will be null and void for the compiler.
