Today's plan
Posix calls
- for a complete list, see e.g. here
under System Interfaces
- may be implemented as system calls or library functions
- include generic math and string functions
- calls defined in the textbook, p. 23, Figure 1-9
- notable additions (i.e., calls in POSIX but not in the textbook):
- networking calls such as socket,
connect,
bind,
listen,
accept,
send,
recv,
shutdown,
- calls for mapping files, such as void * mmap(void *start,
size_t length, int prot, int flags, int fd, off_t offset) and
int munmap(void *start, size_t length)
- posix threads calls such as pthread_create
- poll or select to check open file descriptors
for I/O availability
