ssize_t attribute_hidden _cs_write(void *cookie, const char *buf, size_t bufsize)
{
return write(*((int *) cookie), (char *) buf, bufsize);
}
what does cs stand for here? (Hm.. seems like custom streams..in the code) and I couldn't follow past write above. Where is the function write defined?
Hi Chan,
write is a system call.
$ man 2 write
syscall table for x86 architecture can be found in : <path>/arch/x86/syscalls/syscall_32.tbl
# cat <path>/arch/x86/syscalls/syscall_32.tbl | grep 'write'
4 i386 write sys_write
The format is:
<number> <abi> <name> <entry point> <compat entry point>
search sys_write definition in kernel source.
Thanks
Mohan L
