19.1.3 Parsing Namestrings Into Pathnames</H2> <P>
|
|
Parsing is the operation used to convert a <A REL=DEFINITION HREF="26_glo_n.htm#namestring"><I>namestring</I></A> into a <A REL=DEFINITION HREF="26_glo_p.htm#pathname"><I>pathname</I></A>. Except in the case of parsing <A REL=DEFINITION HREF="26_glo_l.htm#logical_pathname"><I>logical pathname</I></A> <A REL=DEFINITION HREF="26_glo_n.htm#namestring"><I>namestrings</I></A>, this operation is <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A>, because the format of <A REL=DEFINITION HREF="26_glo_n.htm#namestring"><I>namestrings</I></A> is <A REL=DEFINITION HREF="26_glo_i.htm#implementation-dependent"><I>implementation-dependent</I></A>. <P>
|
|
A <A REL=DEFINITION HREF="26_glo_c.htm#conforming_implementation"><I>conforming implementation</I></A> is free to accommodate other <A REL=DEFINITION HREF="26_glo_f.htm#file_system"><I>file system</I></A> features in its <A REL=DEFINITION HREF="26_glo_p.htm#pathname"><I>pathname</I></A> representation and provides a parser that can process such specifications in <A REL=DEFINITION HREF="26_glo_n.htm#namestring"><I>namestrings</I></A>. <A REL=DEFINITION HREF="26_glo_c.htm#conforming_program"><I>Conforming programs</I></A> must not depend on any such features, since those features will not be portable. <P>
