Hello.
I'm using ArchLinux. It runs "/etc/rc.local" at boot. If I start
PulseAudio with "lock-memory = yes" in "/etc/rc.local" with the line
{{{
sudo -u user env HOME=/home/user pulseaudio &
}}}
it yields an error:
{{{
shm.c: mmap() failed: Resource temporarily unavailable
core.c: failed to allocate shared memory pool. Falling back to a normal
memory pool.
shm.c: mmap() failed: Resource temporarily unavailable
core.c: pa_mempool_new() failed.
main.c: pa_core_new() failed.
}}}
But PulseAudio starts smoothly with the same configuration if I start it
from "bash".
I tried to narrow a problem. My test program below runs smoothly from
"/etc/rc.local" and from "bash". What else can I test?
{{{
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/mman.h>
#ifndef _POSIX_MEMLOCK
#error we need the function "mlockall"
#endif
int main (int argc, char **argv) {
char *p;
int n;
int i;
n = 1<<26;
mlockall(MCL_CURRENT | MCL_FUTURE);
p = mmap(NULL, n, PROT_READ|PROT_WRITE, MAP_ANONYMOUS|MAP_PRIVATE,
-1, (off_t) 0);
if (p == MAP_FAILED) {
printf("error while allocating\n");
return (220);
} else {
printf("%d bytes were allocated\n", n);
for (i=n; i-->0;) {
p[i] = 9;
}
return (0);
}
}
}}}
