MAT_VARGETNUMBEROFFIELDS(3)

πŸ’… MAT_VARGETNUMBEROFFIELDS(3) β€” the matio manual, but make it cute

okay bestie, this one lives in the Library Functions Manual section of the matio docs, and it's genuinely one of the shortest little slays in the whole library. no cap. let's get into it πŸ’–


✨ NAME ✨

Mat_VarGetNumberOfFields β€” gets you the number of fields in a structure variable. that's it, that's the whole job πŸŽ€


🌸 SYNOPSIS 🌸

#include <matio.h>

unsigned
Mat_VarGetNumberOfFields(const matvar_t *matvar);

πŸ¦‹ DESCRIPTION πŸ¦‹

so like, the Mat_VarGetNumberOfFields() function returns the number of fields for the structure variable matvar. that's the vibe. you hand it a struct, it tells you how many fields are living inside it. literally that simple 🫢


⭐ RETURN VALUES ⭐

on success you get the number of fields back. on not-success you get 0.

⚠️ and here's the plot twist, bestie β€” a structure can validly contain 0 fields. so if you get a 0 back, don't immediately spiral. it might be an error, or it might just be a struct that's lowkey empty and thriving. the function does not tell you which. main character ambiguity πŸ’€

πŸ‘‘ SEE ALSO πŸ‘‘

  • Mat_VarGetStructFieldnames(3) β€” the bestie function that gets you the actual names instead of just the count. obsessed with her, honestly.
