Running component (without pid).
Here is the caller graph for this function:

◆ parse_definitions()

static int parse_definitions ( const char *  constname,
int  force 
)
static

Utility function - parses a definition.

Definition format: component;file;function;from_line-to_line;level[/component...] All entries are mandatory, but may be empty. Empty entries for component, file and function are treated as "matches anything". Empty line entry is treated as "from 0 to INT_MAX" Line entry with only one line is treated as "this line only" Entry for level MUST NOT be empty. Entries for component, file and function that consist of a single character "*" are treated (at the moment) the same way empty entries are treated (wildcard matching is not implemented (yet?)). file entry is matched to the end of FILE. That is, it might be a base name, or a base name with leading directory names (some compilers define FILE to absolute file path).

Parameters
constnamename of the environment variable from which to get the string to be parsed
force1 if definitions found in constname are to be forced
Returns
number of added definitions
