Clearing a string (char array)

[piranha]

Uh, is there a better way to clear a string then just:

Code: Select all

for(i=0;i<128;i++) str[i] = '\0';

Because it gets old typing that......-JL

memset?

Do you need to clear the string? Often, for ASCIIZ strings it's enough to do:

Code: Select all

str[0] = '\0';

I recommend using aligned buffers for 4 bytes in each iteration using any general purpose register (GPR) or using 8 bytes per iteration using MMX. Putting 1 byte per iteration is really not a good idea in my opinion.

Which means, memset.

Thanks, it did work with just str[0] = '\0'

Cool
