SVC_IO_Write
Writes up to the size bytes from the user source buffer to the I/O output buffer (a.k.a. "reply" or "response" buffer). Returns the size actually written (if the capacity of the output buffer is reached the returned size can be smaller than the requested size).
Synopsis
unsigned int SVC_IO_Write(FmMsgHandle token, void *source, int size);
Syntax options
SVC_IO_Write8
SVC_IO_Write16
SVC_IO_Write32
Similar to SVC_IO_Read8/16/32(), but for writes to the reply buffer.
unsigned int SVC_IO_Write8(FmMsgHandle token, uint8_t v); unsigned int SVC_IO_Write16(FmMsgHandle token, uint16_t v); unsigned int SVC_IO_Write32(FmMsgHandle token, uint32_t v);
