Availability:C-language interface function
int Sfread(void *data, size_t size, size_t elems, IOSTREAM *s)
int Sfwrite(const void *data, size_t size, size_t elems, IOSTREAM *s)
Emulations of the POSIX fread() and fwrite() calls for Prolog streams. These functions read or write elems objects of size size and return the number of objects successfully read or written. Data exchange is binary (even if the stream is in text mode) and unlike read() and write(), these functions keep reading or writing until end-of-file (for Sfread()) or an error.
