ureadc - add character to a uio structure
#include <sys/uio.h> #include <sys/types.h> int ureadc(int c, uio_t *uio_p);
Architecture independent level 1 (DDI/DKI).
The ureadc() function transfers the character c into the address space of the uio(9S) structure pointed to by uio_p, and updates the uio structure as for uiomove(9F).
0 is returned on success and EFAULT on failure.
The ureadc() function can be called from user, interrupt, or kernel context.
