strjoin
Concatenates two specified strings and returns the resulting string.
string strjoin(const char *string1, const char *string2)
The strjoin
function returns the concatenation of two specified strings.
The returned string is allocated out of scratch memory and is therefore valid only during
processing of the clause. If insufficient scratch memory is available,
strjoin
doesn't run and an error is generated.
