NAME¶
i2o_cntxt_list_add - Append a pointer to context list and return a id
SYNOPSIS¶
u32 i2o_cntxt_list_add(struct i2o_controller * c, void * ptr);
ARGUMENTS¶
c
controller to which the context list belong
ptr
pointer to add to the context list
DESCRIPTION¶
Because the context field in I2O is only 32-bit large, on 64-bit the pointer is to large to fit in the context field. The i2o_cntxt_list functions therefore map pointers to context fields.
Returns context id > 0 on success or 0 on failure.
