mprotect
MPROTECT(2) BSD System Calls Manual MPROTECT(2)
NAME
mprotect -- control the protection of pages
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/mman.h>
int
mprotect(void *addr, size_t len, int prot);
DESCRIPTION
The mprotect() system call changes the specified pages to have protection prot. Not all implementations will guarantee protection on a page
basis; the granularity of protection changes may be as large as an entire region.
The protections (region accessibility) are specified in the prot argument by OR'ing the following values:
PROT_EXEC Pages may be executed.
PROT_READ Pages may be read.
PROT_WRITE Pages may be written.
PROT_NONE No permissions.
RETURN VALUES
Upon successful completion, a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error.
ERRORS
[EACCES] A memory protection violation occurred, or the PROT_EXEC flag was attempted on pages which belong to a filesystem mounted
with the NOEXEC flag.
[EINVAL] An invalid memory range, or invalid parameters were provided.
[ENOMEM] A resource shortage occurred while internally calling uvm_map_protect(9).
SEE ALSO
madvise(2), mincore(2), msync(2), munmap(2)
HISTORY
The mprotect() function first appeared in 4.4BSD.
