Dear all,
How can i unset arrays. I mean all the subscripts including the array after using them.
Could you direct me to some links of array memory handling in the korn shell.
Thanks (2 Replies)
PHP question...I posted this on the Web Development forum, but maybe this is a better place!
I have an SQL query that's pulled back user IDs as a set of columns. Rather than IDs, I want to use their names.
So I have an array of columns $col with values 1,7,3,12 etc and I've got an array $person... (3 Replies)

Hi, I hope the title does not scare people to look into this thread but it describes roughly what I'm trying to do. I need a solution in PHP.
I'm a programming beginner, so it might be that the approach to solve this, might be easier to solve with an other approach of someone else, so if you... (0 Replies)

I've noticed something interesting in C++ programming. I've always done tricky stuff with pointers and references to have functions deal with arrays. Doing exercises again out of a C++ book has shown me an easier way, I didn't even know was there. It's weird to me.
When dealing with arrays, it... (4 Replies)

memccpy, memchr, memcmp, memcpy, memmove, memset - memory operations

void *s1, *s2;
size_t n;
Description
These functions operate efficiently on memory areas (arrays of characters bounded by a count, not terminated by a null character). They do
not check for the overflow of any receiving memory area.
The subroutine copies characters from memory area s2 into s1, stopping after the first occurrence of character c has been copied, or after
n characters have been copied, whichever comes first. It returns a pointer to the character after the copy of c in s1, or a NULL pointer
if c was not found in the first n characters of s2.
The subroutine returns a pointer to the first occurrence of character c in the first n characters of memory area s, or a NULL pointer if c
does not occur.
The subroutine compares its arguments, looking at the first n characters only, and returns an integer less than, equal to, or greater than
0, according as s1 is lexicographically less than, equal to, or greater than s2.
The subroutine copies n characters from memory area s2 to s1. It returns s1.
The subroutine is like , except that if s1 and s2 specify overlapping areas, works as if an intermediate buffer is used.
The subroutine sets the first n characters in memory area s to the value of character c. It returns s.
Restrictions
The subroutine uses native character comparison, which is signed on PDP-11s, unsigned on other machines.
Character movement is performed differently in different implementations of and Thus overlapping moves, using these subroutines, may yield
unpredictable results.
