MEMINS(3) C Programmer's Manual MEMINS(3)NAMEmemins - insert bytes at beginning of memory block
SYNOPSIS
#include <publib.h>
void *memins(void *tgt, size_t tgtsize, const void *src, size_t srcsize);
DESCRIPTIONmemins 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.
RETURN VALUEmemins returns its first argument.
EXAMPLE
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.
