The size of the memory area to be allocated is passed as a parameter.
When calling the sbrk routine continuously, memory areas should be
allocated in succession starting from lower addresses. If the memory area for
allocation is insufficient, an error should occur. When allocation is
successful, the address of the beginning of the allocated memory area is
returned; if unsuccessful, (char *) -1 is returned.
Normal:
Error:
size
Returns the address of the error number of the current task.
This routine is necessary when using a standard library, which was created
by the standard library configuration tool with the reent option specified.
Address of the error number of the current task
Waits and acquires the semaphore specified by semnum.
When semaphore has been allocated normally, 1 is returned. Otherwise, 0 is
returned. This routine is necessary to use a standard library which was
created by the standard library configuration tool with the reent option
specified.
