Function Documentation

tree_cell* nasl_chomp

(

lex_ctxt *

lexic

)

Todo:

evaluate early break

tree_cell* nasl_eregmatch

(

lex_ctxt *

lexic

)

Does extended regular expression pattern matching.

In NASL, this function returns an array.

tree_cell* nasl_insstr

(

lex_ctxt *

lexic

)

Syntax: insstr(s1, s2, i1, i2) or insstr(s1, s2, i1) Insert string s2 into slice [i1:i2] of string s1 and returns the result Warning: returns a CONST_DATA!

tree_cell* nasl_str_replace

(

lex_ctxt *

lexic

)

str_replace(string: s, find: f, replace: r [,count: n])

tree_cell* nasl_stridx

(

lex_ctxt *

lexic

)

Returns index of a substring.

Returning NULL for "not found" is dangerous as automatic conversion to to integer would change it into 0. So we return (-1).

Returns:

-1 if string not found, otherwise index of substring.

strstr

tree_cell* nasl_substr

(

lex_ctxt *

lexic

)

Syntax: substr(s, i1) or substr(s, i1, i2) Returns character from string s starting for position i1 till the end or position i2 (start of string is 0)
