int TUnixSystem::RecvBuf ( int  sock,

Length is the size of the buffer. Returns the number of bytes received in buf or -1 in case of error.

int TUnixSystem::RecvRaw ( int  sock,
void buf,
int  length,
int  opt

virtual

Receive exactly length bytes into buffer.

Use opt to receive out-of-band data or to have a peek at what is in the buffer (see TSocket). Buffer must be able to store at least length bytes. Returns the number of bytes received (can be 0 if other side of connection was closed) or -1 in case of error, -2 in case of MSG_OOB and errno == EWOULDBLOCK, -3 in case of MSG_OOB and errno == EINVAL and -4 in case of kNoBlock and errno == EWOULDBLOCK.

Int_t TUnixSystem::RedirectOutput ( const char *  file,
const char *  mode = "a",
RedirectHandle_t h = 0 
)
virtual

Redirect standard output (stdout, stderr) to the specified file.

If the file argument is 0 the output is set again to stderr, stdout. The second argument specifies whether the output should be added to the file ("a", default) or the file be truncated before ("w"). This function saves internally the current state into a static structure. The call can be made reentrant by specifying the opaque structure pointed by 'h', which is filled with the relevant information. The handle 'h' obtained on the first call must then be used in any subsequent call, included ShowOutput, to display the redirected output. Returns 0 on success, -1 in case of error.
