_smalloc()
Allocate memory in blocks
Synopsis:
#include <malloc.h>
void* _smalloc( size_t size );
Arguments:
- size
- The size of the block to allocate, in bytes.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
This function is in libc.a, but not in libc.so
(in order to save space).
Description:
The _smalloc() function allocates space for an object of size bytes. Nothing is allocated when the size argument has a value of zero.
This function allocates memory in blocks of _amblksiz
bytes; _amblksiz is a global variable defined in
<stdlib.h>.
You must use _sfree() to deallocate the memory allocated by _smalloc().
Returns:
A pointer to the start of the allocated memory, or NULL if there's insufficient memory available, or if the requested size is zero.
