Function Documentation

int os_daemonize ( const char *  pid_file)

os_daemonize - Run in the background (detach from the controlling terminal) : File name to write the process ID to or NULL to skip this Returns: 0 on success, -1 on failure

Definition at line 42 of file os_none.c.

void os_daemonize_terminate ( const char *  pid_file)

os_daemonize_terminate - Stop running in the background (remove pid file) : File name to write the process ID to or NULL to skip this

Definition at line 48 of file os_none.c.

int os_get_random ( unsigned char *  buf,
size_t  len 
)

os_get_random - Get cryptographically strong pseudo random data : Buffer for pseudo random data : Length of the buffer Returns: 0 on success, -1 on failure

Definition at line 53 of file os_none.c.

int os_get_time ( struct os_time t)

os_get_time - Get current time (sec, usec) : Pointer to buffer for the time Returns: 0 on success, -1 on failure

Definition at line 29 of file os_none.c.

int os_mktime ( int  year,
int  month,
int  day,
int  hour,
int  min,
int  sec,
os_time_t t 
)

os_mktime - Convert broken-down time into seconds since 1970-01-01 : Four digit year : Month (1 .. 12) : Day of month (1 .. 31) : Hour (0 .. 23) : Minute (0 .. 59) : Second (0 .. 60) : Buffer for returning calendar time representation (seconds since 1970-01-01 00:00:00) Returns: 0 on success, -1 on failure

Note: The result is in seconds from Epoch, i.e., in UTC, not in local time which is used by POSIX mktime().

Definition at line 35 of file os_none.c.

void os_program_deinit ( void  )

os_program_deinit - Program deinitialization (called just before exit)

This function is called just before a program exists. If there are any OS specific processing, e.g., freeing resourced allocated in os_program_init(), it should be done here. It is also acceptable for this function to do nothing.

Definition at line 77 of file os_none.c.

int os_program_init ( void  )

os_program_init - Program initialization (called at start) Returns: 0 on success, -1 on failure

This function is called when a programs starts. If there are any OS specific processing that is needed, it can be placed here. It is also acceptable to just return 0 if not special processing is needed.

Definition at line 71 of file os_none.c.

unsigned long os_random ( void  )

os_random - Get pseudo random value (not necessarily very strong) Returns: Pseudo random value

Definition at line 59 of file os_none.c.

char* os_readfile ( const char *  name,
size_t *  len 
)

Definition at line 94 of file os_none.c.

char* os_rel2abs_path ( const char *  rel_path)

os_rel2abs_path - Get an absolute path for a file : Relative path to a file Returns: Absolute path for the file or NULL on failure

This function tries to convert a relative path of a file to an absolute path in order for the file to be found even if current working directory has changed. The returned value is allocated and caller is responsible for freeing it. It is acceptable to just return the same path in an allocated buffer, e.g., return strdup(rel_path). This function is only used to find configuration files when os_daemonize() may have changed the current working directory and relative path would be pointing to a different location.

Definition at line 65 of file os_none.c.

int os_setenv ( const char *  name,
const char *  value,
int  overwrite 
)

Definition at line 82 of file os_none.c.

void os_sleep ( os_time_t  sec,
os_time_t  usec 
)

os_sleep - Sleep (sec, usec) : Number of seconds to sleep : Number of microseconds to sleep

Definition at line 24 of file os_none.c.

int os_unsetenv ( const char *  name)

Definition at line 88 of file os_none.c.

void* os_zalloc ( size_t  size)

os_zalloc - Allocate and zero memory : Number of bytes to allocate Returns: Pointer to allocated and zeroed memory or NULL on failure

Caller is responsible for freeing the returned buffer with os_free().
