Nope. I just happened to be helping somebody debug a seg-fault in their code caused by pointer-arithmetic error & we ended up in this "philosophical discussion".
His point was to suggest that if a "\0" made it
into the string, the simple use of strlen() or strnlen() would not do "what he wants" (basically a simple socket-based string messenger). Trying to understand his point, I asked if what he was planning on sending/receiving strings with NULL characters in them... to which he responded quite obviously "No".
I was just trying to ascertain if there really was some performance/reliability/speed/efficiency to be gained in
not using strlen() or strnlen(). I thought there legitimately might be, but now I am second-guessing, and simply thinking the guy is nuts to write his own function for something so simple... especially since he got it wrong

hello,
i have a problem with strlen. I have written this:
for(y=13,z=0; cInBuf!=' ';y++)
{
cBuf=cInBuf;
z++;
}
len = strlen(cBuf);
out=len/2;
fprintf(outfile,"F%i",out);
If strlen is e.g. 22, it write F22. I want to write F2F2.
How can i do this?... (5 Replies)

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)

My OS (Debian) and gcc use the UTF-8 locale. This code says that the char size is 1 byte but the size of 'a' is really 4 bytes.

This function was copied into my code, which was compiled without error/warning, but when executed there is always Segmentation fault at the end after the output (which seems correct!):
