SYNOPSIS¶

#include <roaraudio.h>

ssize_t roar_vs_read (roar_vs_t * vss, void * buf, size_t len, int * error);

ssize_t roar_vs_write(roar_vs_t * vss, const void * buf, size_t len, int * error);

DESCRIPTION¶

roar_vs_read() reads data from the sound server into buffer buf.

roar_vs_write() writes data in buffer buf to the sound server.

PARAMETERS¶

vss

The VS object data is read from or written to.

buf

The buffer to read to or write from.

len

The length of the data to be read or written in byte.

error

This is a pointer to a integer used to store the error value in case of error. This can be NULL if not used but it is very recommended to use this error value to report good error messages to the user.
