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.

Parameters

dirname

Directory to add

Definition at line 183 of file srcpos.c.

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().

Parameters

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

Returns

pointer to opened FILE
