Detailed Description

Unit tests for the Xen netback driver.

Due to the driver's use of static functions, these tests cannot be compiled standalone; they must be #include'd from the driver's .c file.

Definition in file netback_unit_tests.c.

Macro Definition Documentation

◆ SNCATF

#define SNCATF	(	buffer,
		buflen,
		...
	)

Value:

        do {                            \
        size_t new_chars = snprintf(buffer, buflen, __VA_ARGS__);       \
        buffer += new_chars;                                            \
        /* be careful; snprintf's return value can be  > buflen */      \
        buflen -= MIN(buflen, new_chars);                               \
} while (0)
