Using Mapfiles
Defining Syntax for Mapfile Directives
Defining Syntax for Mapfile Directives
A mapfile can have zero or more mapfile directives. There are two types
of mapfile directives: segment declarations and section mapping
directives. The directives can span across lines and are terminated by a
semicolon.
The following syntax conventions are used to describe the directives:
• [...]* means zero or more
• [...]+ means one or more
• [...] means optional
• The section_names and segment_names are the same as a C identifier
except that a period (.) is treated as a letter.
• A number can be hexadecimal, following the same syntax as the C
language.
• The section, segment, file, and symbol names are case-sensitive.
• A string of characters following # and ending at a new-line is
considered a comment.
