Detailed Description

Definition at line 66 of file uxposixipc.hpp.

Public Member Functions

void open (const char *name, int flags, mode_t perms=PERM_FILE)
void unlink (const char *name)
void * mmap (size_t len, void *addr=NULL, int prot=PROT_READ|PROT_WRITE, int flags=MAP_SHARED, off_t off=0)
void munmap (void *addr, size_t len)

Member Function Documentation

void * PosixShm::mmap (  size_t  len,
void *  addr = NULL,
int  prot = PROT_READ | PROT_WRITE,
int  flags = MAP_SHARED,
off_t  off = 0
) 
 

Calls mmap. Arguments are in a different order to take advantage of defaults, and fd argument comes from the class.

Definition at line 188 of file uxposixipc.cpp.

References errno, and Ux::File::fd.

void PosixShm::munmap (  void *  addr,
size_t  len
) 
 

Calls munmap. Could be static, as it doesn't refer to the fd.

Definition at line 200 of file uxposixipc.cpp.

References errno.

void PosixShm::open (  const char *  name,
int  flags,
mode_t  perms = PERM_FILE
) 
 

Calls shm_open.

Definition at line 161 of file uxposixipc.cpp.

References errno, and Ux::File::fd.

void PosixShm::unlink (  const char *  name  ) 
 

Calls shm_unlink. Could be static, as it doesn't refer to the fd.
