matho_parse(3) Symbolic Math Library matho_parse(3)NAMEmatho_parse - Process Mathomatic expression or equation input
SYNOPSIS
int matho_parse(char *input, char **outputp);
DESCRIPTION
Parse a mathematical equation or expression and store in the next
available equation space, making it the current equation. Afterwards,
it can be operated on by Mathomatic commands using matho_process(3).
matho_init(3) must have been called only one time before this to ini‐
tialize the Mathomatic symbolic math engine. Use matho_clear(3) as
many times as you want to restart Mathomatic for the next group of
operations.
The input and output ASCII strings are expressions, if successful. The
expression or equation string to enter is in "input", the resulting
output string is stored in "*outputp". The equation number of the
equation space that the output expression is additionally stored in (if
any) is available in the global "result_en", otherwise result_en = -1.
Works the same as matho_process(3), except commands are not allowed, so
that variables are not ever confused with commands. In fact, this
function is currently set to only allow entry and storage of expres‐
sions and equations.
Returns true (non-zero) if successful.
