input: src is the string we look in for needle. |

Needle may be escaped by a backslash, in |
| 946 |
that case we ignore that particular needle. |
| 947 |
return value: returns next src pointer, for |
| 948 |
succesive executions, like in a while loop |
| 949 |
if retval is 0, then there are no more args. |
| 950 |
pitfalls: |
| 951 |
src is modified. 0x00 chars are inserted to |
| 952 |
terminate strings. |
| 953 |
return val, points on the next val chr after ins |
| 954 |
0x00 |
| 955 |
|
| 956 |
example usage: |
| 957 |
while( (pos = next_arg( optarg, ',')) ){ |

printf("%s\n",optarg); |

optarg=pos; |
