Function Documentation

void srcfile_add_search_path ( const char dirname)

Add a new directory to the search path for input files

The new path is added at the end of the list.

dirnameDirectory to add

int srcfile_pop ( void  )

Definition at line 162 of file srcpos.c.

void srcfile_push ( const char fname)

Definition at line 143 of file srcpos.c.

FILE* srcfile_relative_open ( const char fname,
char **  fullnamep 

Open a source file.

If the source file is a relative pathname, then it is searched for in the current directory (the directory of the last source file read) and after that in the search path.

We work through the search path in order from the first path specified to the last.

If the file is not found, then this function does not return, but calls die().

fnameFilename to search
fullnamepIf non-NULL, it is set to the allocated filename of the file that was opened. The caller is then responsible for freeing the pointer.
