i2o_cntxt_list_add(9)
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.
