Define Documentation

#define gd_init (  gd, desc   )

For internal use only. This helper macro initializes a generator descriptor with the specified description. Parameters: [in]  gd  A pointer to the ev_gendesc_t to be initialized. [in]  desc  A pointer to a struct generator containing the description of the generator. Definition at line 60 of file event_gen_register.c. Referenced by gens_construct(), gens_extend(), and gens_merge().

#define gens_link (  ctx, gens   )

For internal use only. This macro is used to link a set of generator descriptors, as specified in the gens argument, into the linked list of generator descriptors. The gens structure must already have its next and prev pointers set. Parameters: [in]  ctx  A pointer to the containing ev_ctx_t. [in]  gens  A pointer to an ev_gens_t to be linked into the list of generators. Definition at line 88 of file event_gen_register.c. Referenced by gens_construct(), gens_extend(), and gens_merge().

Function Documentation

static ev_err_t gens_construct (  ev_ctx_t *  ctx, ev_gens_t *  prev, ev_gens_t *  next, struct generator *  desc )  [static]

For internal use only. This function is a helper function to create a new ev_gens_t containing a description of one generator, as specified by the desc parameter. Parameters: [in]  ctx  A pointer to the containing ev_ctx_t. [in]  prev  A pointer to the previous ev_gens_t in the generator list. [in]  next  A pointer to the next ev_gens_t in the generator list. [in]  desc  A pointer to a struct generator containing the description of the generator. Return values: ENOMEM  Out of memory. Definition at line 119 of file event_gen_register.c. References _ev_ctx_s::ec_maxgen, ev_return, ev_trace, gd_init, gens_link, generator::gentype, _ev_gens_s::gs_count, _ev_gens_s::gs_first, _ev_gens_s::gs_gens, _ev_gens_s::gs_next, and _ev_gens_s::gs_prev. Referenced by event_gen_register().

static ev_err_t gens_extend (  ev_ctx_t *  ctx, ev_gens_t *  gens, struct generator *  desc )  [static]

For internal use only. This function is a helper function to extend an existing ev_gens_t to include a description of a new generator, as specified by the desc parameter. Parameters: [in]  ctx  A pointer to the containing ev_ctx_t. [in]  gens  A pointer to the ev_gens_t to be extended. [in]  desc  A pointer to a struct generator containing the description of the generator. Return values: ENOMEM  Out of memory. Definition at line 167 of file event_gen_register.c. References _ev_ctx_s::ec_maxgen, ev_assert, ev_return, ev_trace, gd_init, gens_link, generator::gentype, _ev_gens_s::gs_count, _ev_gens_s::gs_first, and _ev_gens_s::gs_gens. Referenced by event_gen_register().

static ev_err_t gens_merge (  ev_ctx_t *  ctx, ev_gens_t *  gens, struct generator *  desc )  [static]

For internal use only. This function is a helper function to merge two ev_gens_t structures into a single ev_gens_t containing all the generators of the two being merged and the one specified by the desc parameter. It is only called when the new generator has a type one greater than the last generator in gens and one less than the first generator in the ev_gens_t following gens in the linked list. Parameters: [in]  ctx  A pointer to the containing ev_ctx_t. [in]  gens  A pointer to the first of two ev_gens_t to be merged. [in]  desc  A pointer to a struct generator containing the description of the generator. Return values: ENOMEM  Out of memory. Definition at line 224 of file event_gen_register.c. References _ev_ctx_s::ec_maxgen, ev_assert, ev_return, ev_trace, gd_init, gens_link, generator::gentype, _ev_gens_s::gs_count, _ev_gens_s::gs_first, _ev_gens_s::gs_gens, _ev_gens_s::gs_next, and _ev_gens_s::gs_prev.
