Function

Saves logs to a file.

Acl APIs also provide the ACL_APP_LOG macro, which has encapsulated the aclAppLog API. You are advised to pass the variable parameters in the log level, log description, and fmt to the ACL_APP_LOG macro call.

#define ACL_APP_LOG(level, fmt, ...) \
    aclAppLog(level, __FUNCTION__, __FILE__, __LINE__, fmt, ##__VA_ARGS__)

Prototype

void aclAppLog(aclLogLevel logLevel, const char *func, const char *file, uint32_t line, const char *fmt, ...)

Parameters

Parameter	Input/Output	Description
logLevel	Input	Log level. typedef enum { ACL_DEBUG = 0, ACL_INFO = 1, ACL_WARNING = 2, ACL_ERROR = 3, } aclLogLevel;
func	Input	API where aclAppLog is called. The value is fixed at __FUNCTION__.
file	Input	File where aclAppLog is called. The value is fixed at __FILE__.
line	Input	Line where aclAppLog is called. The value is fixed at __LINE__.
fmt	Input	Log description. When the formatting function is called, the type and number of parameters in fmt must be the same as the actual ones.
...	Input	A variable parameter in fmt, added based on the log content. The maximum length of a single log is 1024 bytes. If the length exceeds 1024 bytes, the log will be truncated.

Returns

None

Example

//If fmt contains variable parameters, define them in advance.
uint32_t modelId = 1;
ACL_APP_LOG(ACL_INFO, "load model success, modelId is %u", modelId);
