Method Details

getutxent

FreeBsdLibc.FreeBsdUtmpx getutxent()

Reads a line from the current file position in the utmp file. It returns a pointer to a structure containing the fields of the line.

Not thread safe

Returns:

a FreeBsdLibc.FreeBsdUtmpx on success, and NULL on failure (which includes the "record not found" case)

thr_self

int thr_self(NativeLongByReference id)

Stores the system-wide thread identifier for the current kernel-scheduled thread in the variable pointed by the argument id.

Parameters:

id - The thread identifier is an integer in the range from PID_MAX + 2 (100001) to INT_MAX. The thread identifier is guaranteed to be unique at any given time, for each running thread in the system.

Returns:

If successful, returns zero, otherwise -1 is returned, and errno is set to indicate the error.
