MEMINS(3) C Programmer's Manual MEMINS(3)

memins - insert bytes at beginning of memory block

#include <publib.h>
void * memins(void *tgt, size_t tgtsize, const void *src, size_t srcsize);

memins inserts srcsize bytes from src at the beginning of tgt, but moves the first tgtsize out of the way. The source and target memory blocks must not overlap.

memins returns its first argument.

To insert a new element at the ith position of an array, one might do the following.

int new, array[10];
memins(array+i, (10-i-1)*sizeof(array[0]), &new, sizeof(new));
Please note that the above code carefully avoids the trap of moving the last element of the array past the end of the array.
