using the shm_open() function for shared memory access in linux --regarding

[gunasingh]

Hi all,

I am using the shm_open() function declared in the <sys/mman.h>

I get linker error saying undefined reference to shm_open()
function...

Can anyone tell me where can i find the definition for the method
shm_open() ???

Thanks,

Gunasingh

You need to link with -lrt.

Since shm_open() is specified by POSIX, not by C, you're likely to get
better information in comp.unix.programmer. Your system's
documenation (probably "man shm_open") may also be a good source of
information.
