c - Is there a function to set a process stack/heap memory allocation? -

I know that this is an OS function but there is a way to increase your entire stack or heap size through C ? Is Sbrk () used to change the size of the data segment? Does this mean both stacks and heaps?

The virtual memory OS (when a CPU is used with the MUU) automatically increases the data / stack volume when necessary, up to maximum POSIS system But maximals can be configured using the Satellite (), because W. Craig Trader said. POSIX defines RLIMIT_DATA, RLIMIT_STACK, and RLIMIT_AS.

malloc () uses the BRIC () to grow / shrink internal data segment, or mmap () / munmap () / request / memory mapping to release. The stack has increased when the CPU tries to access the memory below the allotted stack.

On systems with an AMU (like uClinux), the executable file format typically has a field for the stack size, for example, the BFLT file format).
