31.8.17. alt_msgdma_write_standard_descriptor
Prototype: | int alt_msgdma_write_standard_descriptor (alt_u32 csr_base, alt_u32 descriptor_base, alt_msgdma_standard_descriptor *descriptor) |
Include: | < modular_sgdma_dispatcher.h >, <altera_msgdma_descriptor_regs.h> |
Parameters: | csr_base – base address of the dispatcher CSR agent port. descriptor_base – base address of the dispatcher descriptor agent port. *descriptor – a pointer to a standard descriptor structure.
|
Returns: | Returns 0 upon success. Other return codes are defined in "alt_errno.h". |
Description: | Sends a fully formed standard descriptor to the dispatcher module. If the dispatcher descriptor buffer is full, “-ENOSPC” is returned. This function is not reentrant since it must complete writing the entire descriptor to the dispatcher module and cannot be pre-empted. |
