gnutls_record_send(3) gnutls gnutls_record_send(3) NAME
gnutls_record_send - API function SYNOPSIS
#include <gnutls/gnutls.h> ssize_t gnutls_record_send(gnutls_session_t session, const void * data, size_t data_size); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. const void * data contains the data to send size_t data_size is the length of the data DESCRIPTION
This function has the similar semantics with send(). The only difference is that it accepts a GnuTLS session, and uses different error codes. Note that if the send buffer is full, send() will block this function. See the send() documentation for full information. You can replace the default push function by using gnutls_transport_set_ptr2() with a call to send() with a MSG_DONTWAIT flag if blocking is a problem. If the EINTR is returned by the internal push function (the default is send()) then GNUTLS_E_INTERRUPTED will be returned. If GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must call this function again, with the same parameters; alternatively you could provide a NULL pointer for data, and 0 for size. cf. gnutls_record_get_direction(). The errno value EMSGSIZE maps to GNUTLS_E_LARGE_PACKET. RETURNS
The number of bytes sent, or a negative error code. The number of bytes sent might be less than data_size . The maximum number of bytes this function can send in a single call depends on the negotiated maximum record size. REPORTING BUGS

gnutls_ia_recv(3) gnutls gnutls_ia_recv(3) NAME
gnutls_ia_recv - read data from the TLS/IA protocol SYNOPSIS
#include <gnutls/extra.h> ssize_t gnutls_ia_recv(gnutls_session_t session, char * data, size_t sizeofdata); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. char * data the buffer that the data will be read into, must hold >= 12 bytes. size_t sizeofdata the number of requested bytes, must be >= 12. DESCRIPTION
Receive TLS/IA data. This function has the similar semantics with recv(). The only difference is that it accepts a GnuTLS session, and uses different error codes. If the server attempt to finish an application phase, this function will return GNUTLS_E_WARNING_IA_IPHF_RECEIVED or GNUTLS_E_WARN- ING_IA_FPHF_RECEIVED. The caller should then invoke gnutls_ia_verify_endphase(), and if it runs the client side, also send an endphase message of its own using gnutls_ia_endphase_send. If EINTR is returned by the internal push function (the default is code{recv()}) then GNUTLS_E_INTERRUPTED will be returned. If GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must call this function again, with the same parameters; alternatively you could provide a NULL pointer for data, and 0 for size. RETURNS
The number of bytes received. A negative error code is returned in case of an error. The GNUTLS_E_WARNING_IA_IPHF_RECEIVED and GNUTLS_E_WARNING_IA_FPHF_RECEIVED errors are returned when an application phase finished message has been sent by the server. REPORTING BUGS
