#include <linux/prctl.h> /* Definition of PR_* constants */ #include <sys/prctl.h> int prctl(PR_SET_MM, PR_SET_MM_BRK, unsigned long addr, 0L, 0L);
LIBRARY
Standard C library (libc, -lc)
DESCRIPTION
Set the current brk(2) value.
The requirements for the address are the same as for the
PR_SET_MM_START_BRK option.
RETURN VALUE
On success, 0 is returned. On error, -1 is returned, and
errno is set to indicate the error.
ERRORS
- EINVAL
- addr is greater than TASK_SIZE (the limit on the size of the
user address space for this architecture).
- EINVAL
- addr is less than or equal to the end of the data segment or
specifies a value that would cause the RLIMIT_DATA resource limit
to be exceeded.
