Macro Definition Documentation

◆ STATIC_ERR

#define STATIC_ERR (   m)    STATIC_MSG(STDERR_FILENO, m)

Statically allocate a string and write it to STDERR.

Warning
The return value will from atomic_write will be ignored which means that errors will be ignored. This is normally fine as this macro is intended to be used in fatal signal handlers where error handling might not be feasible.

◆ STATIC_MSG

#define STATIC_MSG (   fd,
 
)
Value:
do { \
static const char msg[] = m; \
atomic_write(fd, msg, sizeof(msg) - 1); \
} while (0)

Statically allocate a string and write it to a file descriptor.

Warning
The return value will from atomic_write will be ignored which means that errors will be ignored. This is normally fine as this macro is intended to be used in fatal signal handlers where error handling might not be feasible.
