Function Documentation

proc_frame_ctx_t* proc_frame_ctx_allocate

(

)

Allocate an uninitialized input/ouput processor frame structure.

Returns

Pointer to the newly allocated input/output processor frame structure; NULL if fails.

Definition at line 47 of file proc_if.c.

proc_frame_ctx_t* proc_frame_ctx_dup

(

const proc_frame_ctx_t *

proc_frame_ctx_arg

)

Duplicate an input/output processor frame structure.

Parameters

proc_frame_ctx_arg

Pointer to the input/output processor frame structure to be duplicated.

Returns

Pointer to the new allocated replica of the given input structure; NULL if fails.

Definition at line 52 of file proc_if.c.

void proc_frame_ctx_release

(

proc_frame_ctx_t **

ref_proc_frame_ctx

)

Release an input/output processor frame structure.

Parameters

ref_proc_frame_ctx

Reference to the pointer to the input/output processor frame structure to be released. Pointer is set to NULL on return.

Definition at line 125 of file proc_if.c.

proc_if_t* proc_if_allocate

(

)

Allocate an uninitialized processor interface context structure.

Returns

Pointer to the newly allocated processor interface context structure; NULL if fails.

Definition at line 142 of file proc_if.c.

int proc_if_cmp	(	const proc_if_t *	proc_if1,
		const proc_if_t *	proc_if2
	)

Compares if given processor interfaces are the equal.

Parameters

proc_if1	Pointer to the first processor interface context structure to be compared.
proc_if2	Pointer to the second processor interface context structure to be compared.

Returns

Value 0 if given contexts are equal, otherwise non-zero value is returned.

Definition at line 187 of file proc_if.c.

proc_if_t* proc_if_dup

(

const proc_if_t *

proc_if_arg

)

Duplicate a processor interface context structure.

Parameters

proc_if_arg

Pointer to the processor interface context structure to be duplicated.

Returns

Pointer to a new allocated replica of the given input structure; NULL if fails.

Definition at line 147 of file proc_if.c.

void proc_if_release

(

proc_if_t **

ref_proc_if

)

Release a processor interface context structure.

Parameters

Reference

to the pointer to the processor interface context structure to be released. Pointer is set to NULL on return.
