NAME

allwrite, allwritev - write requested amount of data to a file

SYNOPSIS

#include <limb/allreadwrite.h>

size_t allwrite(int fd, const char *data, size_t dlen)
size_t allwritev(int fd, const struct iovec *v, unsigned n)

DESCRIPTION

The allwrite() function will attempt to write dlen bytes from the memory pointed by data to the file associated with file descriptor fd.

The allwritev() function is similar only writing data as described by the array v of n vectors.

RETURN VALUE

These functions return the number of bytes written, which may be less than dlen (even 0) in case of error.
