Prototype

C Prototype

        
             aclError aclprofGetOpNum(const void *opInfo, size_t opInfoLen, uint32_t *opNumber)

Python Function

        
             op_num, ret = acl.prof.get_op_num(op_info, op_info_len)

Parameter Description

Parameter	Description
op_info	Int, specified memory address. After the size of the single-operator data structure is obtained by calling acl.prof.get_op_desc_size, you must allocate memory based on the value obtained by multiplying the size of the single-operator data structure by the integer coefficient. The memory is used to store operator data collected by Profiling and is used as the input of this API.
op_info_len	Int, length of the operator information.

op_info_len

Int, length of the operator information.

Return Value Description

Return Value	Description
op_num	Int, number of operators.
ret	Int, error code. 0 indicates success. Other values indicate failures.
