Member Function Documentation

destroy()

int condy::FdTable::destroy ( )

inlinenoexcept

Parameters

capacity

The number of file descriptors to allocate in the table

Returns

int Returns 0 on success or a negative error code on failure

Definition at line 34 of file ring_settings.hpp.

set_file_alloc_range()

int condy::FdTable::set_file_alloc_range ( unsigned offset, unsigned size )

inlinenoexcept
