long pack_fread(void *p, long n, PACKFILE *f);
DESCRIPTIONReads `n' bytes from the stream `f', storing them at the memory location pointed to by `p'. Example:
unsigned char buf; ... if (pack_fread(buf, 256, input_file) != 256) abort_on_error("Truncated input file!");
RETURN VALUEReturns the number of bytes read, which will be less than `n' if EOF is reached or an error occurs. Error codes are stored in errno.
