arm_get_correlator_flags: get value of flag
NAMEarm_get_correlator_flags - get value of flag
DESCRIPTIONarm_get_correlator_flags() returns the value of a specified flag in the correlator header.
A correlator header contains bit flags. arm_get_correlator_flags() is used to test the value of those flags. See arm_generate_correlator() for a description of a correlator.
corr_flag_num is an enumerated value that indicates which flag's value is requested. The enumerated values are:
- 1 (ARM_CORR_FLAGNUM_APP_TRACE) = Application trace flag
2 (ARM_CORR_FLAGNUM_AGENT_TRACE) = Agent trace flag
correlator is a pointer to a buffer containing a correlator. It serves no purpose to make the call if
the pointer is null.
flag is a pointer to a boolean that is output indicating whether the flag is set.
RETURN VALUEOn success, the function returns ARM_SUCCESS. A non-zero value indicates an error.
ERRORSIf the return code is negative, an error occurred. If the return code is not negative, an error may or may not have occurred - the determination of what is an error and whether an error code is returned is at the discretion of the ARM implementation. The application can test the return code if it wants to provide its own error logging.
The following errors are recognized by this implementation, but may not be portable to other implementations:
- The correlator and flag arguments must not be null.
- An unknown flag value has been specified.
