◆ LogError()

char* CrashLogUnix::LogError ( char *  buffer,
const char *  last,
const char *  message 
) const
inlineoverrideprivatevirtual

Writes actually encountered error to the buffer.

Parameters
bufferThe begin where to write at.
lastThe last position in the buffer to write to.
messageMessage passed to use for possible errors. Can be nullptr.
Returns
the position of the '\0' character after the buffer.
