2.3.18. aocl_mmd_hostchannel_get_buffer
The aocl_mmd_hostchannel_get_buffer function provides a host with a pointer to the buffer they can access to write or read from the channel interface, along with the space or data available in the buffer, in bytes.
Syntax
void *aocl_mmd_hostchannel_get_buffer( int handle, int channel, size_t *buffer_size, int *status );
Function Arguments
- handle—A positive int value representing the handle to the board obtained from the aocl_mmd_open() call.
- channel—A positive int value representing handle to the channel to close obtained from the aocl_mmd_hostchannel_create() call.
- buffer_size—A pointer to size_t that the function writes available buffer space or size to.
- status—A pointer to int that the function writes result of the call to.
Return Value
If the function executes successfully, int pointed to by the status pointer is 0. Returned void* may still be NULL, in which case size_t pointed by the buffer_size is 0.
If the function fails to execute, int pointed by the status pointer is a negative value.
