Detailed Description

Header for Dr. Syscall system call records.

Macro Definition Documentation

SYSCALL_RECORD_UNION_SIZE_BYTES

#define SYSCALL_RECORD_UNION_SIZE_BYTES   (sizeof(uint8_t *) + sizeof(size_t))

To enable syscall_record_t to be default initialized reliably, a byte array is defined with the same length as the largest member of the union.

Typedef Documentation

syscall_record_t

typedef START_PACKED_STRUCTURE struct syscall_record_t_ syscall_record_t

Describes a system call number, parameter, memory region, or the return value.

Enumeration Type Documentation

syscall_record_type_t

enum syscall_record_type_t

The type of the syscall record.

Enumerator
DRSYS_SYSCALL_NUMBER	Start of a syscall.
DRSYS_PRECALL_PARAM	Pre-syscall parameter.
DRSYS_POSTCALL_PARAM	Post-syscall parameter.
DRSYS_MEMORY_CONTENT	Memory address, size, and content.
DRSYS_RETURN_VALUE	Return value of the syscall.
DRSYS_RECORD_END	End of a syscall.
