13 # ./argdist -p 2420 -c -C 'p:c:malloc(size_t size):size_t:size'
46 # ./argdist -c -H 'p:c:write(int fd, void *buf, size_t len):size_t:len'
84 # ./argdist -c -H 'p:c:write(int fd, void *buf, size_t len):size_t:len:fd==1'
119 You can also use argdist to trace kernel functions. For example, suppose you
123 # ./argdist -i 3 -n 2 -H 'p::__kmalloc(size_t size):size_t:size'
146 # ./argdist -i 10 -n 1 -C 'p:c:puts(char *str):char*:str'
159 # ./argdist -i 10 -n 1 -C 'r:c:gets():char*:(char*)$retval:$retval!=0'
169 # ./argdist -i 10 -c 1 -H 'r:c:read()'
